Folks,

I'm running 2.1-STABLE and have been experiencing a problem with news feeds
stuck in a CLOSE_WAIT state.  It seems only a reboot will fix it.  What is
causing this and can I clear it without rebooting?

Innd reports:

Netstat reports:

tcp        0      0  venus.nntp             newsie.dmc.com.1296    CLOSE_WAIT

The processes marked as established are delivering news normally.  As you
can see they come from the same source so the "No route to host" message is
in error.

Any pointers are appreciated.


Thanks,

Craig
