My cyrii run on Solaris, so I'm not familiar with what platform specific issues you may be having. You might try running just squatter one night without expire and see how it does. Also, make sure you're running squatter with the option (think it's - s) that makes it only reindex mailboxes that have changed since the last squatter run. -rob Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html

Squatter shouldn't be causing "load spikes" unless there's some resource contention for lock files, etc. You should also make sure that if you're running cyr_expire, you're NOT running it concurrently with squatter. Bad things happen.* To get around this, I created a "nightly" shell script which runs cyr_expire, then squatter, and kick that off as a scheduled task in my cyrus.conf. * The bad things come into play if expire & squatter are processing the same mailbox at the same time.

Squatter causing load spike
I am running squatter at 3am as a cron job on all of my servers. Over the passed week I have one server where squatter spikes the load and ends up locking up the server at around 8am every morning. Yeah, it seems to take that long to run which may be an issue in itself. Has anyone come accross this or have a suggestion on how to get squatter to perform better?
