Hi,
after upgrade to dovecot 2.2.31 (ee) some users (very few) have problem
to see, via IMAP, their folders after login. The error in the log is
simple master: service(imap): child 15528 killed with signal 11 (core
dumped). The user see only the INBOX folder. We are using Director and NFS.
Below my configuration and the backtrace.
Thanks
