Environment

GWAVA (Secure Messaging Gateway)

Situation

High utilization and high load average on SMG on SLES appliance.

Resolution

If the load average and utilization is really high on the server, run 'top' to see which processes are the busiest:


If the processes at the top are bdamserver and freshclam then do the following:

1) In the above screenshot 'freshclam' has been running for almost 2.5 hrs and is most likely stuck on getting an update. This service is not needed if ClamAv is not being used. ClamAv is off by default but freshclam is active to get AV updates in case ClamAv is enabled. To see if ClamAv is disabled login to the vaadmin console httsp://server:9443, go to system tools and see if the ClamAv service is running or not.



2) If ClamAv is not being used, then it is safe to disable the freshclam service. Do the following to disable it:

a) From a server prompt type: service freshclam stop


b) Type the following to prevent it from starting up again after a server reboot: systemctl disable freshclam

If the utilization doesn't go down, reboot the server to stop it from trying to get the update. Upon restart it shouldn't load and try to update again.
