Very high CPU Usage constantly for FOG Services on physical Storage Node
-
Hi,
i am experiencing very high cpu usage on my storage node.
I have a fog master virtualized and a pyhsical storage node:Both machines are on trunk 7919 Before i upgraded there was also a heavy load on the system, i upgraded from a trunk version 2-3 days old.

@x23piracy just guessing these systems are Ubuntu?
For some reason the installer is unable to stop the fog services. Everything else goes off without and issue. This should be fixed if you stop the fog services and start them back up. They get into an infinite loop because the next time they check in they lose what their sleep time was which gets interpreted as zero. As they’re in a loop, they take up a lot of cpu.

@Tom-Elliott is this also needed after a reboot of the system? It’s 14.04.4 i already rebooted after update

@x23piracy I had the same issue. The only way I could fix it is restart the services as root. A full reboot didn’t do it for me. I use a script and added these commands at the end to do so (must be root! I run a cron job as root to do this):
service FOGMulticastManager stop && sleep 5 && service FOGMulticastManager start service FOGPingHosts stop && sleep 5 && service FOGPingHosts start service FOGImageReplicator stop && sleep 5 && service FOGImageReplicator start service FOGSnapinReplicator stop && sleep 5 && service FOGSnapinReplicator start service FOGScheduler stop && sleep 5 && service FOGScheduler start

i can also repeat restarting the services but itsS the same:
