Hi,

        Mailscanner is configured with exim and spamassassin and
currently it has got some Zombie processes. This is the strace from one
of the processes.

       EAGAIN shows that it cannot get lock on a file and ENOTTY relates
to why mailscanner is looking for a character file.

       has this it do with the confguration of the mailscanner. I am
having quite a large output queue which does not get cleared on its own.

       Has any one experienced this before.

        umask(0133)                             = 077

        open("/mail/spool/exim.in/input/1HUTuF-0000Mj-DU-H", O_RDWR|
        O_LARGEFILE) = 6
        ioctl(6, SNDCTL_TMR_TIMEBASE or TCGETS, 0xbfeb3b78) = -1 ENOTTY
        (Inappropriate ioctl for device)
        _llseek(6, 0, [0], SEEK_CUR)            = 0
        fstat64(6, {st_mode=S_IFREG|0640, st_size=1191, ...}) = 0
        fcntl64(6, F_SETFD, FD_CLOEXEC)         = 0
        fcntl64(6, F_SETLK64, {type=F_WRLCK, whence=SEEK_SET, start=0,
        len=0}, 0xa4c0988) = -1 EAGAIN (Resource temporarily
        unavailable)
        close(6)                                = 0
