I dont know what is writing to flash and is going from 85% ~ 100% at 2 hours uptime .

Anyone else has the same problem ?

The problem has been found on 751G and 951G routers . About 10 of them need restart to fix .

Thanks.

i had the same issue and the mikrotik's support recomend me to upgrade to v6.7 and it will fix. I don't try yet because the router can be reboot. You can try it.

All my routers has been upgraded to the latest RouterOS version with latest Firmware .

I cant understand why that happend

I have same problem.
Does RB750 support 6.XX or it increase CPU usage?
I am using 10mbps bandwidth, client under 100 person,
usermanager, no web proxy.

Thanks

did you enable proxy option?

I have got indications from support that it could be caused by to little free memory. How much free memory do you have when this happens?

Flash means writing to disk (or in this case, NAND). What processes are running? Have you configured logging to disk, graphing, proxy?

Hello
logging to disk not configured,
graphing yes but not stored on disk
proxy is not enabled but it shows running.
please check screenshot.

Thanks
