Hi
We run a 100 user imapd server (cyrus 2.1.15 and db 4.1.25) which is having a huge amount of problems with the delivery and tls databases (both in Berkeley DB) becoming corrupted and killing the mail server. I have searched the mail list and it appears that this is not an uncommon problem with solutions being down grade DB version to some thing prior to 4.1.25 or use skiplist.
Anyway we have had so much fun we are building a new server with cyrus-imapd 4.2.5. At the moment I am trying to figure out if I just give up on Berkeley and use skiplist for delivery and tls databases or try Berkeley DB 4.2.52. With 100 users we are not talking a heavy load so the performance advantages of BDB over skiplist would not be massive. I guess I would be interested if anyone has had problems with cyrus-imapd and BDB 4.2.52. Also if anyone has done any bench marking on the effect of skiplist vs bdb in real world mail serving.
Cheers Matt Cocker
