Please let the list know if you do find a trigger... We've been hitting
something similar and I don't have any excuses for not attempting to fix
it. I'm lazy, other people appear to be busy, etc :)
By "big" I mean on the order of 60-90 megabytes. Not gigantic by any
means. No real tunables I know of... If you don't want to restart your
tracker, it's been floated (though I haven't tried yet) just reaping and
restarting the replicators by cron until we get this fixed out.
!want 0 replicate
!want 2 replicate
