[Xymon] no client results arrive, lot of TIME_WAIT at server

[Thomas Eckert]

Norbert,

I assume your manual (BB way) is something like `xymon 1.2.3.4 “status example.com.test …”`.

The xymon-client send `clientdata` that is processed by a “channel listener” and _that_ sends status-messages similar to above (a bit simplified).

That channel-listener may not be running/crashing:
Check our `tasks.cfg` for the section `[clientdata]` and verify, if the `xymond_channel`-process is running (I suspect it’s not). Maybe the `clientdata.log` helps with debugging. You may also run the task manually to get further information.

What’s your problem with the "lot of TIME_WAIT”? Are these just for tcp/1984-connections?

Cheers
Thomas
