We have a loop going that sometimes takes quite a while (https://github.com/hubblestack/hubble/blob/develop/hubblestack/extmods/modules/pulsar.py#L726). Occasionally, if the loop takes too long or something happens externally during the loop, some of the watches seem to disappear doing the
process_events(). I'm not totally sure what causes it. Is it the kernel canceling the watch and thereforeget_watch(raw_event.wd)is failing? are we externally modifying the watchlist during theprocess_events()? Not sure. What I can say is that it's always very shortly lived temp files that trigger this error.I'm confident the missing watches are safe to ignore. The 30,000 hosts reporting this error for /opt/specialthing/whatever is wasting quite a lot of space in our log analyzer. And we'd really rather keep watching the specialthing/whatever directory, even though it has quite a lot of tempfiles that pop in/out.
Let me know if you think this is a wrongheaded way to solve the problem or have a better idea what else we could fix.
Thanks.
