    root@server [/] ulimit -n 922222

    did the trick
    restart exim - no more error

    but again no emails were transported

    as mailscanner service was stopped - restarted mailscanner now it works.

    how can i set the ulimit to a fixed size - so in case of reboot this wont happen again?

    sysctl -a | grep fs.file-max
    fs.file-max = 13055535

    more /proc/sys/fs/file-nr
    135168 0 13055535

    lsof | wc -l
