We have a 3G P4 with 2GB ram box, RouterOS 3.10 and Userman package.

The box is not under heavy load yet the CPU load goes up day by day.

The box is currently acting as Userman radius server for pppoe clients who
connect to pppoe servers set up at each node.

The box also does NAT for every pppoe network from the different nodes.

Right now, we don´t have more than 20 customers... so there should be
no load problem..

If I reboot the server, CPU load starts low and the gradually gets up again.

Here is a graph of CPU from boot up a week ago.

Anyone having a similar problem or any thoughts as to what might be causing it?

Try to disable unused packages from the /system package and check...

Do you use dynamic queues?
Check and be sure that they are correctly configured.
Chech the rate limit in the usermanager.
If things continues that way, backup your userman database and install a fresh copy of the ROS preferrably a higher version this time.
Then load your usermanager backup file into the database.
If things does not change then U may need to post your configurations

Thanks for the replies, ashish was spot on.

Old dude package was installed in the server and was generating lots of traffic and connections, as if it were doing constant discoveries.

Problem solved.

Thanks,
Santiago.
