Hi sbr-services,
Could you give me some idea?
### abrt reported the error as below. [root@cupop4 log]# abrt-cli list --since 1488267244 id ad716dbfd3a68bbe0f055e32ebfe562f4f75df43 reason: imap killed by SIGBUS time: Sun Mar 19 2017 10:58:27 AM JST cmdline: dovecot/imap package: dovecot-2.2.10-7.el7 uid: 80180 (acaa2325) count: 2 Directory: /var/spool/abrt/ccpp-2017-03-19-10:58:27-4904 'abrt-cli report を実行する/var/spool/abrt/ccpp-2017-03-19-10:58:27-4904'
### /var/log/messages Mar 19 10:58:27 cupop4 abrt-hook-ccpp: Process 4904 (imap) of user 80180 killed by SIGBUS - dumping core
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?
