Cyrus users, I have been having a problem with my cyrus 2.2.13 install over the last couple of days. First I keep getting this DBERROR log: -------------------------------------------------------------------- Jul 1 15:37:55 server lmtpunix[18456]: DBERROR db4: 49980 lockers -------------------------------------------------------------------- Several messages I read on the list stated to ignore it, it wasn't a big deal, however this doesn't seem to apply on larger installations that eventually fill the lock table: -------------------------------------------------------------------- Jul 1 15:42:50 server imaps[20139]: DBERROR db4: Lock table is out of available locker entries Jul 1 15:42:50 server imaps[20139]: DBERROR: opening /var/spool/imap/tls_sessions.db: Cannot allocate memory Jul 1 15:42:50 server imaps[20139]: DBERROR: opening /var/spool/imap/tls_sessions.db: cyrusdb error Jul 1 15:47:05 server lmtpunix[21385]: DBERROR db4: Lock table is out of available locker entries Jul 1 15:47:05 server lmtpunix[21385]: DBERROR: opening /var/spool/imap/deliver.db: Cannot allocate memory Jul 1 15:47:05 server lmtpunix[21385]: DBERROR: opening /var/spool/imap/deliver.db: cyrusdb error -------------------------------------------------------------------- So now we have a problem, the database quits and eventually becomes corrupted: -------------------------------------------------------------------- Jul 1 15:47:06 server lmtpunix[20989]: DBERROR db4: 50000 lockers Jul 1 15:47:07 server lmtpunix[21391]: DBERROR db4: Lock table is out of available locker entries Jul 1 15:47:07 server lmtpunix[21391]: DBERROR db4: PANIC: Cannot allocate memory Jul 1 15:47:07 server lmtpunix[21391]: DBERROR: critical database situation Jul 1 15:47:07 server lmtpunix[21407]: DBERROR db4: PANIC: fatal region error detected; run recovery -------------------------------------------------------------------- So now the question is how do I fix this? I am running BDB-4.2.52 with all 4 patches so the only thing I can do with bdb is to upgrade to the 4.4.20 release, but I'm unsure if this release is any more stable. My mailboxes file seems safe since it is in skiplist format, so maybe I should convert the deliver database to skiplist as well? What about cyrus 2.3.6? Is this stable enough for a large server? Does it work around any of the BDB problems?
