[Xymon] Fwd: Xymon 4.3.2 http flapping with SSL error

This usually means that connecting to the service failed. There might be 
some additional information in the xymonnet logfile.

The "sslcert" column (I assume that is the one you mean) only reports 
the status of the SSL certificate; it it cannot connect to the server 
then there is no certificate to report on, and hence that status is not 
updated (and will eventually go purple).

If increasing the timeout doesn't help, perhaps you can use something 
like "badhttp:3:3:5" to delay alerting until the test has failed for 
more than one poll cycle ? This example would cause it to go yellow for 
3 poll cycles (15 minutes) and red after 5 cycles (25 minutes).
