High CPU load since update to 9.704-2

sdengscherz

Hey there, last night we installed 9.704-2 on our 2-node A/P SG230 cluster.

Since the reboot we encounter unusually high CPU load:

Has anyone seen this behaviour? What can we do?

Regards, -sd

 

 

EDIT: Wireless seems also pretty unstable, connections to AD authenticated SSIDs dropping...

    Hallo,

    Whenever something like this happens right after applying Up2Dates, the first thing to try is restoring the 'Automatic Backup' made before the Up2Date was applied.  If that doesn't fix the problem, reboot.  Agreed with H_Patel that you should get a ticket open if this issue persists.

    Assuming you're still having the issue, what do you see if you watch top at the command line, what processes are using the most CPU?  Also, is the %sy spiking?

    Cheers - Bob

    Hello Bob,

     

    thanks for your reply, top shows different processes spiking - including snort, proxy, and mdw; logs are also growing unusually large.

     

    I have opened a support request already.

     

    Regards, -sd
