<p><font size=2>Could it comes from how the xymonproxy program handles
the MACHINE variable ?</font><font size=3> <br>
</font><font size=2><br>
I say that because when the process becomes nuts, he makes only 'gettimer'
action. Then I have a look in the source file and found this line (line
452) that could correspond:</font><font size=3> <br>
</font><font size=2><i><br>
if (proxyname && ((now = gettimer()) >= (laststatus+300))) {</i></font>
<p><font size=2>[snip]</font>
<p><font size=3>Last Sunday, I wanted to start a xymonproxy (vers 4.3.12)
on a Solaris 10.5 with 900 targets . I had a performance issue: </font>
<p><font size=2>- The xymonproxy process used 100% of only one CPU (no
multithread seen).</font><font size=3> </font><font size=2><br>
- On the main XYMON server, data from this proxy (I have one other on Ubuntu
with 50 targets working fine) came with difficulties (delays and lacks).</font><font size=3>
</font>
<p><font size=3>I suspect some kind of error happened with the network
socket handling. Could you add this patch and try to reproduce the problem?
It doesn't change the behaviour, but it does add some error-reporting in
case the core select() call fails.</font>
