Hi,
after to upgrade to dovecot-2.2.25 I see some killed with signal 11 in
the log file:
Jul 18 08:41:59 pop01 dovecot: pop3(rossi at milano.it): Fatal: master:
service(pop3): child 32318 killed with signal 11 (core dumped)
Jul 18 09:22:48 pop01 dovecot: imap(mail_backup at domain.it): Fatal:
master: service(imap): child 16137 killed with signal 11 (core dumped)
I’m not sure but I think happens with new users at the first login but
I’m not able to reproduce it.
Here the backtrace:
Core was generated by `dovecot/pop3 pop3-postlogin'.
Program terminated with signal 11, Segmentation fault.
