i have problems in 3.14 and 3.15 ver with dual core, it works in 3.11 before
I have motherboard ASrock with 2,0 ghz procesor dual core and the time go 5X or moore.
system hardware set multi-cpu=no" is not a solution i have try... and the same problem after 30 min.

Mikrotik ros 3.15 is hanging/freezing after some minutes of operating with the dual core.
We have to force reboot the system after that!!!
The same situation with 3.14. (we are not facing the same problem with the 3.13 but hotspot problems).

Exactly we have some core2duo based server, reboots every 5min on 3.14, we had to change gateway to old P4 3.0HT on Intel Server motherboard and now works without problem. For example linux with latest kernel and xen enabled runs well on that machine... eh ;)

HI

I confirm problem with time and simple queues on dual core procesors. Problem is from version 3.14 & 3.15 not solved, 3.13 works fine. I hawe AMD ATHLON X2 64bit procesor. From version 3.14 on my case statistics on mt webpage graphs shows not existing interface - interface was removed a long time ago.

I upgraded my old MT server to Core2Duo processor and after a half
hour it shows me 50% load ... and have some jumps to 100%, and one more
strange thing happens ... System Clock runs faster 30 sec instead 1,
it runs no much longer and MT serv crashes. I decide to set BIOS at
fail safe mode. After that time goes ok .. but CPU load shows me 0% after
10-15min of uptime.

My PC config:
MT: v3.15
CPU: Core 2 Duo E4500
MB: MSI on IntelG31 chipset
RAM: 2x512Mb Kingston
LAN: 1xRTL8111/8168B PCI Express Gigabit Ethernet controller
3xRTL-8169 Gigabit Ethernet

My system make exactly the same...clock jumps 10-20 seconds, CPU usage 50% and after a wile it stays at 100% an hang but sometimes I can enter with winbox on mac and reboot. Deactivating dual core works.
AMD X2 cpu with 1GB ram and intel NIC's

i have same problem with 3.15
3.13 worked fine, but then i upgrade it to 3.15 clocks on my routers start jump 5-10 seconds, and through some time i can't reach router with winbox or ssh

I have the same problem, what can i do??? downgrade to 3.what?? what is stable??? sure taht 3.13 works fine?? because i change it again and still the same problem, probaly i lose my job because this means that lose clients for this problem.

I downgraded to v3.7 and system works fine

I've replace with an older single core PC and is working now. Nice.

back from 3.15 to 3.13 - it's work!

Same here, see minutes shoot up one min per second. Without multi-core, no issues.

Any updates MT?

Any news about this issue with version 3.16?

ROS 3.16 released, there's a line in Changelog:

fixed problem - x86 clock was 10 times faster then it should be on some boards;

Just tried it, now time goes only two times faster than real... ;(

i think we should stick to 2.9.51

Tested 3.16 and still have 100% CPU. On my system, this happens after 10-14 hours of uptime. Stepped back to 3.13.

Configure NTP client to keep the system synchronised to an Atomic clock while we await a fix for the issue

Make sure you send supouts to support@mikrotik.com. As well as reference to this tread is always helpful.

Mikrotik 3.16 on Supermicro MBD-X7DWA-N still come unusable after 15/20 min.
If run torch, much faster.
After this, supout file, can not be done.

Mikrotik less then 3.15 don't recognize intel 82575 nic.

I stalled.

Please tell us exact motherboard name that you use. ASrock is just a brand. We will need exact motherboard model, so we can buy some for testing.

Just an idea - aren't it all Intel chipsets?

normis : http://www.supermicro.com/products/moth ... 7DWA-N.cfm

It looks like everyone experiencing these problems have motherboards with Intel 5xxx Chipset.
For istance, I am using an IBM HS21XM blade server which has a Intel 5000P Chipset.

Am I wrong?

It would be great to get support output files to support@mikrotik.com
from Everyone who has problems with "fast" clock on x86 box with the 3.16 version and the latest BIOS installed.
Thank you very much.

I have installed latest BIOS but mikrotik could not boot with latest bios.

More detailed information is required about the used hardware.

Clock problem still exists in RouterOS 3.16 with our dual core Intel CPU. Uptime leaps 27 seconds every second. Here is our router hardware:

Intel Celeron E1200 1.6GHz LGA 775 65W Dual-Core Model BX80557E1200
Foxconn G31AX-K LGA 775 Intel G31 ATX Intel Motherboard
Kingston ValueRAM 512MB 240-Pin DDR2 SDRAM DDR2 667 (PC2 5300) KVR667D2N5/512

We have a spare unit with the same configuration available for testing. Please let us know how we can help.

Thanks,

Here is Motherboard link

And the cpu link
http://processorfinder.intel.com/detail ... Spec=SLACR

We are also having clock problems on versions 3.14 and up (even with 3.16). We are back to using 3.6, which does not have this problem.

Our mobo is Asus P5KPL-AM (G31 Chipset)
http://www.asus.com/products.aspx?model ... 3=563&l4=0

We're not doing any overclocking or anything else, standard install.

I've problems with 3.16 and dual CPU. 10 sec. Clock jump. Working fine in 3.13.
IBM x330 server.

Please, contact support department about the problem (support@mikrotik.com)/

Working fine on HP ML 110 Pentiun D multicpu-on

Working fine on HP ML 110 Pentiun D multicpu-on

Great!
But Subject is Dual Core problem!

Working fine on HP ML 110 Pentiun D multicpu-on

Great!

As far as i know PENTIUM D is a DUAL CORE ( Dual Pentium 4 CPU)


"The Pentium D brand refers to two series of dual-core 64-bit x86 processors with the NetBurst microarchitecture manufactured by Intel. Each CPU comprised two single-core dies (CPUs) - next to each other - in one Multi-Chip Module package. "

gustkiller :
what cpu usage on your server?
how much pps?
how long its working without reboot?

My supermicro X7DWA-N with 2 xeon work normally to, without traffic,
only when traffic go higher then 200mbit/s, appear the problem.

no reboot since upgrade, 4 days , 120 ~ 130mbits / 50Mbits about 35kpps ( 65kpps agregated ). cpu about 35, 40%.


before deployment i leave it doing a btest udp 64bytes packet for 2 days.

network cards are a Dual port intel pro 1000 server, and a onboard gigabit broadcom nic.

System: Intel Pentium IV 2.4 on Intel motherboard
ROS version 3.0-3.16
Problems:
system hangs after 12-15 hours of work
PPTP server service is not responding (disappear?) for 2-5 minutes (clients can't connect to PPTP server)
heavy CPU load (system can't transfer more than 100Mbps due to 100% CPU load)

System: Intel Pentium IV 3.0 HT on Asus DeLuxe motherboard
ROS version 3.0-3.13
multicore=yes
Problems:
system time is slow than real for 10 minutes per hour
PPTP server service is not responding (disappear?) for 2-5 minutes (clients can't connect to PPTP server)

multicore=no
system hangs afrer 1-2 hours of work
PPTP server service is not responding (disappear?) for 2-5 minutes (clients can't connect to PPTP server)

ROS verion 3.14-3.16
multicore=yes
system time is faster than real
PPTP server service is not responding (disappear?) for 2-5 minutes (clients can't connect to PPTP server)

multicore=no
actual queue rate is 1/2 than rate in rules (example: clients queue rule is 256k, really client has 128k)
PPTP server service is not responding (disappear?) for 2-5 minutes (clients can't connect to PPTP server)

could it be a problem with dual-core only and not dual cpu?

Same problem here with HP prolient ML110 G4 server Dual Xeon processor.
Runs OK until the router is stressed in some way, running the bandwidth test tool for example.
CPU usage goes high and stays there, even without any load.
Clock starts jumping several seconds per tick
All statistics are wrong by the same factor
Queues go at the wrong speed

Rebooting sets things back to normal
It seems to me (no direct evidence for this) that the second core is only called upon when the system is stressed in some way. That is when things start to go wrong.

Running the server in single core mode is OK

its sounding like a problem with intel core duo / new xeon architecture..

noone with pentium 4 dual core ( pentium D ) posted any problem in this topic.

Can anyone plz tell me, which version is stable for dual core. i have tried with v3.13, but freezing.

PPTP server crashes are the bug for PPTP server itself IMO since already being discussed in other threads.

gustkiller:

You're running 3.7, which is also not causing these clocking issues on our Intel Core 2 Quad systems running on Asus motherboards. These problems started to happen when we upgraded to 3.13 and above. Since then, we've gone back to using 3.6 / 3.7 and no more clocking issues. However, those versions have the occasional PCQ lock-up issue.

Can anyone plz tell me, which version is stable for dual core. i have tried with v3.13, but freezing.

raktim

Magically freezing problem has solved in v3.13. i think its stable v3.13
