dotlock causing crashes
OS: CentOS 7 x86_64 Dovecot version: 2.2.31 (65cde28) (GhettoForge RPM) Filesystem: GlusterFS, but working on changing that. Only one server is receiving activity. Was getting messages about corrupt dovecot.map.index files. Changed to dotlock from fcntl to try to fix that. Reading symbols from /usr/libexec/dovecot/imap...(no debugging symbols found)...done.
