[Xymon] Purple storm

[Poppy, Ben]

I have an interesting problem that happened last night. We are working on a DR test. Part of that test includes shutting down some DC's in our DR datacenter. When that happened, most tests that are initiated from the xymon servers (http, dns, ssh, ftp, etc) to the monitored server went purple. The servers that went purple were not all in our DR datacenter, it was at all of our sites, and even included some tests to the xymon server itself (we monitor the HTTP web page of xymon itself as well).

Both of our xymon servers point to 2 windows DC's in our production datacenter in /etc/resolv.conf for DNS lookups.

Has anyone run into this before? Any ideas how it could be related? Or how to fix/prevent it?

We are running 4.3.4.

Thanks,
-Ben
