UTM 9.705-3 - continuous high cpu utilization - multiple rrdtool processes

Hello everyone!

Since yesterday 00:35 UTC the CPU utilization on my Sophos UTM is continuously on 100%

The Sophos runs on a virtual machine with 8GB memory and 2 cores with 3.80GHz.

After restarting the firewall, it is at 50% CPU for some time, until it jumps up again to 100% and stays there.

I did not change any setting immediately prior to this problem coming up.

I sshd into the machine to see what processes are running and found the following with `ps auxf`

root     12205  0.0  0.0   4464   612 ?        S    01:55   0:00  \_ /usr/sbin/cron

cron seems to start rrdtool processes, which seem to be stuck. and it will start more and more of the processes over time.

Things I have tried:

  • I have tried to kill the rrdtool processes but they just respawn.
  • I have tried to remove all cached results because I thought that less data might make it easier for the process
  • I have setup a new VM with a fresh install of the firewall where I restored my config

Here also a picture of my Hardware Reporting: (Around 19:00 yesterday was when I tried the new VM instance)



Please let me know what logs I can supply to help you understand my problem :)
