Hi folks
I've just spotted a large number of ctl_cyrusdb process that appear to
have hung, for no apparent reason:

The master was restarted on April 13, which is when the oldest of the
ctl_cyrusdb instances appears to have been started.
Thankfully the processes only use about a megabyte of memory each, so I
can afford to let them accumulate for a while (especially since they'll
probably be swapped out anyway).
I suspect I have berkley db problems (woohoo!) but any suggestions or
comments would be appreciated. I have a plain text copy of my mailboxes
list, and a fresh backup.
Perhaps now is a good time to upgrade to 2.2 and skiplist ;-) since the
more I have to deal with Berkley DB, the less I want to have to deal
with it.
I don't know if these db sizes are reasonable:
[root at bucket imap]# du -h mailboxes.txt.`date -I` mailboxes.db db/*
16K mailboxes.txt.2004-04-14
36K mailboxes.db
8.0K db/__db.001
264K db/__db.002
40K db/__db.003
13M db/__db.004
32K db/__db.005
8.5M db/log.0000000004
given that we get relatively small mail volumes here.
