I've been having issues with load on my xymon proxy causing it to miss some tests. It's usually a custom test run via cron at the same time by a dozen machines.

My question is what is the timeout for your custom tests on that server. If it were 10 minutes, I would blame the normal update got missed by the server, but 2 in a row is a stretch unless you had a big load on the server.

We recently had a problem where all the standard test columns on a Linux client turned purple for 20 minutes and then resolved themselves. During this time 4 custom tests on that server were working ok.

I've looked through logs and can't find anything that gives me any clues as to why this could have happened.

Has anyone any idea why it might turn purple like this and then resolve itself with no outside intervention?

Any more details about the server? Does it have NFS mounts?

(Far fetched, but I've seen NFS problems cause "df" to hang so Xymon can't finish collecting data and then the server goes purple...)
