Slowing down state manager after unhandled error
Subsystems (2)
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

It got dropped for 3.6 simply because it was at the end of a patch series that was truncated in the middle. I'm submitting it again for 3.7.
