Hi,
I can add a detail, every time I get the "panic error" on the replica
node, I had one minute before this log written on the first node:
/dic 14 11:04:50 xxx dovecot[16715]:
doveadm(xxx)<16454><uKbQLCJsuGFGQAAAIQnY6g>: Error: Couldn't lock
/mnt/mail-storage-lv0007/xxx/.dovecot-sync.lock:
fcntl(/mnt/mail-storage-lv0007/xxx/.dovecot-sync.lock, write-lock,
F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held by
pid 16215)/
Regards
