Thanks! The trac<->git changeset browser obviously has to grind through the repo all the time, so this is the likely candidate for io load. But the repo isn't all that large all things considered, it should easily fit into memory. Some filesystem tuning might be really benefitial, in particular

The physical machine that Trac is running has been experiencing heavy disk IO from different processes for the past 3 days, which is likely contributing to the problems. The image file is also located on a ZFS volume, and I've seen odd issues with ZFS recently. I think I will move Trac to the n

Yes, we should allow indexing of tickets but not of the timeline and the changeset browser. On Friday, October 11, 2013 8:32:15 PM UTC+1, William wrote: > > On Fri, Oct 11, 2013 at 11:55 AM, Volker Braun > > > wrote: > > Trac isn't using any swap. It is pulling quite a lot of CPU load. > Loo

Trac isn't using any swap. It is pulling quite a lot of CPU load. Looking at the log, it seems somebody is indexing trac and pulling up old changesets and timeline (both are notoriously slow in trac). For example: http://trac.sagemath.org/timeline?from=2009-05-06T13%3A17%3A39-07%3A00&precision=s

Trac is back up. Something causes Trac to use nearly 100% CPU and memory after running for a few weeks, and eventually it becomes impossible to ssh into the VM running it. For the time being I'll put a monitor on Trac's memory use and try to restart it before it gets to the point of locking up.
