100% CPU on RB951G-2HnD while copy files between DMZ and LAN

RouterOS General

Hi,

I never noticed that behavior, but maybe it’s my fault and it’s normal behavior. When I copy some big data from LAN to DMZ or reverse, Mikrotik goes on 100% CPU, which maybe is OK, but also kills some of other connections (apcupsd network clients reports lost connection to UPS master, CAPSman remote CAPS are disconnected) and in the end Mikrotik reboot itself.

Should I downgrade FW ? I upgraded to a new FW two days ago.

Now I setup DMZ interface to 100M only and CPU is going about 70-90%, CAPS are OK and other stuffs too.

I definitely not aware about killing connections while copying files before or disconnecting CAPS

The RB951G isn´t the most Powerful Router of the World…
You can expect around 244 Mbps of Routing capacity (without FastPath)

Solutions…

  • Firewall / NAT Optimisation
  • Fast Path utilisation
  • QoS / bandwidth-Limitation


    If you need more help, please post the config of the Mikrotik device
    (/export hide-sensitive file=anynameyouwish)
