<p style="margin-top:0;margin-bottom:0">We've had a similar problem with another service. Looking at the xymonnet man page, there doesn't appear to be a general timeout (http, yes, but not generally). I use an expect script (as an external test) where I can
spawn a process (in this case the ldap call). I set a timeout in expect, so if the spawned connection hangs, the timeout triggers and terminates the connection.<br>

<div>We've run xymon for years, and BB for years before that. We've recently <br>
bumped into a potential problem with xymonnet. In the middle of the <br>
night, all of our tests populated by xymonnet went purple. We think <br>
we've tracked the problem, and attribute it to an ldap query which took <br>
too long to respond. It looks like xymonnet just stopped while it waited <br>
for this query to complete. While it was waiting on this response, none <br>
of the other xymonnet tests were being performed.<br>
<br>
The man for xymonnet indicates there is a --timeout=N which determines <br>
how long to wait for a service to accept a connection. Is there some <br>
parameter which will control how long xymonnet can try to get an answer <br>
after connecting?<br>
