<p class="MsoNormal">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.

<p class="MsoNormal">All the false reports are really damaging
the trust we place in Xymon to monitor our systems, and people
are starting to just delete the warning emails without looking
at them because we get so many false reports now.

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>
