Subject: Slowing down state manager after unhandled error
Date: Fri, 17 Aug 2012 19:57:31 +0530 [thread overview]
Message-ID: <502E54D3.4010103@suse.com> (raw)
Hi Trond and Chuck,
Recently, we have had a report on production SLES system where the
system's CPU utilization went very high due to the state manager
constantly sending huge number of requests every second due to an
unhandled error. The following patch from Chuck
https://patchwork.kernel.org/patch/1185421/
mitigated this issue. Would be interested to know whether this patch
queued up already or you see any problem with the approach.
Thanks
Suresh
