Possibly a kernel bug. On a busy system, there should be one dbsblog process holding an exclusive lock on: /var/spool/postfix/pid/unix.dbsblog this process should be blocked in an accept(2) system call. If clients are trying to connect, but that process remains blocked, your kernel is buggy. -- Viktor.
