Description of problem:

I have some repeateable problem with xinetd under RH9, it fails to
infinite loop and has to be restarted manually, here is the sample:

$ ps axfw
28663 ?        R    8394:10 xinetd -stayalive -pidfile /var/run/xinetd.pid
19683 ?        Z      0:00  \_ [popa3d <defunct>]
20709 ?        Z      0:00  \_ [popa3d <defunct>]
21154 ?        Z      0:00  \_ [popa3d <defunct>]
21216 ?        Z      0:00  \_ [popa3d <defunct>]

How reproducible:

The problem is that I can't provide exact steps to reproduce that, but
probably that's related to some memory shortage. I just notice such
situation quite often on loaded machines.

Any help on how to track that problem more precisely is welcome.

Comment 2 Jay Fenlason 2004-06-03 14:23:55 EDT
Red Hat Linux 9 is out of support these days.  If you can reproduce
the problem with the more recent xinetd included in Fedora Core 2,
open a new bug on it.
