<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.

</span></strong><span style="font-size:12.0pt;font-family:"Times New Roman","serif"">in the xymon environment? 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>
