Hi sbr-services,
Could you give me some idea?
### abrt reported the error as below.
[root at cupop4 log]# abrt-cli list --since 1488267244 id

And, there are lots of ldap error in /var/log/messages. Dovecot uses the
ldap as userdb and passwddb.
Is the ldap error related to imap crash?

Please keep responses on list. Can you please run valgrind on this, as it appears to be some sort of memory corruption issue.
