Hi, I've been running cyrus-imap for a few years not. I am using 2.4.17-8 on ClearOS (a Centos derivative). I've been running with "delprune cmd="cyr_expire -E 1 -X 7 -D 7" at=0001" in cyrus.conf, but in the last week or so it has started segfaulting. I've tried moving the command to cron.daily "/usr/lib/cyrus-imapd/cyr_expire -E 1 -X 7 -D 7" but it still segfaulting. In /var/log/maillog I get: Mar 12 03:15:53 server cyr_expire[15065]: Repacking mailbox user.mail-ebay Mar 12 03:15:53 server master[15064]: setrlimit: Unable to set file descriptors limit to -1: Operation not permitted Mar 12 03:15:53 server master[15064]: retrying with 4096 (current max) Mar 12 03:15:53 server cyr_expire[15065]: Repacking mailbox user.mail-ebay.Drafts Mar 12 03:15:54 server cyr_expire[15065]: Repacking mailbox user.nick Mar 12 03:15:54 server cyr_expire[15065]: Repacking mailbox user.ourfamily Mar 12 03:15:54 server cyr_expire[15065]: Repacking mailbox user.ourfamily.Drafts Mar 12 03:15:54 server cyr_expire[15065]: Expunged 0 out of 9150 messages from 57 mailboxes Mar 12 03:15:54 server cyr_expire[15065]: duplicate_prune: pruning back 0.00 days Mar 12 03:15:54 server ctl_cyrusdb[15068]: recovering cyrus databases Mar 12 03:15:55 server ctl_cyrusdb[15068]: skiplist: checkpointed /var/lib/imap/mailboxes.db (57 records, 4816 bytes) in 0 seconds Mar 12 03:15:55 server ctl_cyrusdb[15068]: skiplist: checkpointed /var/lib/imap/annotations.db (0 records, 144 bytes) in 0 seconds Mar 12 03:15:55 server ctl_cyrusdb[15068]: done recovering cyrus databases Mar 12 03:15:55 server master[15064]: unable to setsocketopt(IP_TOS): Operation not supported Mar 12 03:15:55 server ctl_cyrusdb[15073]: checkpointing cyrus databases Mar 12 03:15:55 server ctl_cyrusdb[15073]: done checkpointing cyrus databases Mar 12 03:15:55 server imaps[15075]: error sending to idled: 3 Mar 12 03:15:55 server imap[15074]: error sending to idled: 3 Mar 12 03:15:55 server imap[15078]: error sending to idled: 3 Mar 12 03:15:55 server imap[15076]: error sending to idled: 3 Mar 12 03:15:55 server imaps[15081]: error sending to idled: 3 Mar 12 03:15:55 server imap[15080]: error sending to idled: 3 Mar 12 03:15:55 server imaps[15077]: error sending to idled: 3 Mar 12 03:15:55 server imaps[15079]: error sending to idled: 3 Mar 12 03:15:56 server tls_prune[15071]: skiplist: checkpointed /var/lib/imap/tls_sessions.db (575 records, 122352 bytes) in 0 seconds Mar 12 03:15:56 server cyr_expire[15072]: skiplist: checkpointed /var/lib/imap/deliver.db (37 records, 5464 bytes) in 0 seconds Mar 12 03:15:56 server cyr_expire[15072]: Expunged 0 out of 9112 messages from 57 mailboxes Mar 12 03:15:56 server cyr_expire[15072]: duplicate_prune: pruning back 3.00 days Mar 12 03:15:56 server cyr_expire[15072]: duplicate_prune: purged 0 out of 37 entries The "error sending to idled: 3" is probably a red herring as cyrus-imap has just restarted following a db backup, so earlier idled connections have broken.

Looks like you might have a corrupted BerlkeyDB . What is the output of ? grep _db /etc/imapd.conf
