deliver db problem

[John Alton Tamplin]

I am running Cyrus 2.1.11 (Solaris 9, mboxlist/seen=skiplist, sub=flat, 
duplicate/tls=db3_nosync), and periodically sieve stops working after 
the server has been up a couple of weeks.  Upon further investigation, I 
find it is some problem with the deliver.db file, as running ctl_deliver 
-d results in "ctl_deliver: unable to init duplicate delivery database". 
 Stopping and restarting master fixes the problem (perhaps because it 
runs ctl_cyrusdb -r?), and ctl_deliver -d dumps the database properly 
after this.  No error messages appear in the logs (even logging at debug 
level) during normal operation, but trying to run ctl_deliver -d logs 
"DBERROR: opening /var/imap/deliver.db: Not enough space".  There is 39G 
free swap space (out of 40G), and the machine has 8G RAM.

Has anyone else seen this problem?  What can I do to get more 
information about what is causing it?
