Hi list
I recently experienced core dumps on one of my dovecot servers:
Apr 30 13:46:49 <ip> dovecot: [ID 583609 mail.error] dovecot: child 4088 (imap) killed with signal 6 (core dumped) Apr 30 13:46:56 <ip> dovecot: [ID 583609 mail.error] IMAP(xx@xx.be): Raw backtrace: 0x80e42f9 -> 0x80e3df3 -> 0x80e9fbe -> 0x80e86d2 -> 0x80da020 -> 0x80e86d2 -> 0x806ff0c -> 0x806e80b -> 0x80671fa -> 0x806b4e1 -> 0x806c1b6 -> 0x806c171 -> 0x806c333 -> 0x806cc8a -> 0x80eb761 -> 0x80eb161 -> 0x8074261 -> 0x80652ec Apr 30 13:46:58 <ip> dovecot: [ID 583609 mail.error] IMAP(xx@xx.be): Raw backtrace: 0x80e42f9 -> 0x80e3df3 -> 0x80e9fbe -> 0x80e86d2 -> 0x80da020 -> 0x80e86d2 -> 0x806ff0c -> 0x806e80b -> 0x80671fa -> 0x806b4e1 -> 0x806c1b6 -> 0x806c171 -> 0x806c333 -> 0x806cc8a -> 0x80eb761 -> 0x80eb161 -> 0x8074261 -> 0x80652ec Apr 30 13:47:00 <ip> dovecot: [ID 583609 mail.error] dovecot: child 4279 (imap) killed with signal 6 (core dumped) Apr 30 13:47:00 <ip> dovecot: [ID 583609 mail.error] dovecot: child 4279 (imap) killed with signal 6 (core dumped)
I went to xx@xxx.be 's maildir, and saw a big file named core: -rw-------+ 1 vpopmail vchkpw 3.9M 2010-04-30 13:47 core
I'm on solaris 10 server, how to analyse this core dump to find what caused it ?
Thanks in advance, Pierre
