If anything, those switches should cause any hidden bugs with
memory handling to be more quickly exposed, even to the point of
aborting.<br>
<br>
Have you noticed any free/alloc issues in xymond.log, or any other
altered behavior since bouncing it?<br>

<p class="MsoNormal" style="margin-left:.5in">Has anyone been
working on the problem where reports from clients are
getting confused on the server? I am getting multiple false
alerts daily now where it will turn back to green at the
next test, and when I go to look at the test in xymon it’s
because it’s only got partial information. In multiple
instances now I’ve been able to see the report from another
client, in part or in full, in one clients page. In the
most recent incident last week I could see the beginning
client line from another windows client report halfway down
in the ports test for a Linux client.

I've noticed this occasionally in the past and added
debugging logic, but I wasn't able to reliably duplicate it.
I noticed that it did seem to happen more often when the
server was under memory pressure and didn't seem to be
related to truncated (or garbled) incoming TCP connections.<br>
<br>
Also, what version and distro?<br>
