Comment(by eharris at puremagic.com):
In case it is helpful, I've narrowed down what seems to be the cause of
the problem. Whenever the backend actually deletes a recording due to the
backend getting below the minimum free space limit, shortly thereafter the
system goes into the highly loaded continuous issuance of SCHEDULE_CHANGE
messages. Just to be clear, this is NOT caused when a program is marked
as deleted, only after the video file is actually deleted. One additional
nuance is that while the load increases significantly (until being "fixed"
by restarting the backend) with a single recording being deleted, it
usually takes two deletions (on my system) before the load goes high
enough to be user-visible and cause problems (video skips, delayed
responsiveness, etc). Three or more deletions usually makes the system
practically unresponsive, so the load generating effect seems to be
cumulative.
I can't tell for sure from trac or the changelog, but has this fix made it
into the 0.21-fixes branch? If so, I will upgrade my system to a later
version that includes the fix to see if it resolves the issue I am seeing.
