[Xymon] xymonnet TCPtest error 4

Hello,

We are running Xymon with xymonnet version 4.3.26-1.el6.terabithia and SSL library : OpenSSL 1.0.1e 11 Feb 2013 (CentOS release 6.8).

Sporadically we see errors testing a certain host with imaps and pop3s tests.

The errors are as follows:

TCPtest error 4 seen on open connection for $x.imaps

TCPtest error 4 seen on open connection for $x.pop3s

.. where $x is a few random extended ASCII characters

A commonality is that these are both SSL/TLS enabled services hosted on the same system. pop3s is configured as port 995 with SSL/TLS required and imaps is port 993 with SSL/TLS required.

My gut tells me this is probably related to SSL/TLS negotiation problems.

Any recommendations on where to start?

Thanks,
