    Hi there,

    Just installed nagios, and it's zombie check script has (about once a week) started reporting Zombie processes. When I check, they are the following:

    502       7062  0.0  0.0      0     0 ?        Z    Feb14   0:00 [freshclam] <defunct>
    502      13245  0.0  0.0      0     0 ?        Z    01:42   0:00 [freshclam] <defunct>
    502      23296  0.0  0.0      0     0 ?        Z    04:06   0:00 [freshclam] <defunct>
    502      27888  0.0  0.0      0     0 ?        Z    06:30   0:00 [freshclam] <defunct>
    I can't kill the processes, and HUPing freshclam doesn't help. The only thing that gets rid of them is to restart the ISPConfig server:

    /etc/init.d/ispconfig_server restart
    Anybody know why they are being left around, and how I can stop them?

    For ref, I'm on ISPConfig v2.2.19

    I have seen these processes too but I have no idea what is causing them.

    Well, in my understanding, Zombies occur when a process terminates, but the parent process fails to reap it's dead children (don't you love unix terminology!). I don't think, in such small numbers, they would ever be a problem, of course. They do seem to dissappear eventually...

    The question is though, why are they there? I would have thought that freshclamd is probably the culprit, so maybe this would be sorted by including a newer version of that in a later release of ISPConfig.

    For now I think I'll just modify the relevant line in Nagios' NRPE config file!
