I think I solved one of the issues with the xymonlaunch errors. I went through the core dump and found that for some reason a root file was created in tasks.d which storing all the mail that root sends out. My account that runs xymon does not have root access so it is no way it can create it. Once that file was deleted, the Task cid:image003.gif at 01D34FFA.21DA2880 terminated by signal 6 errors for xymonlaunch stopped. Very weird.

I restarted xymon and now I am getting these messages:

I am not sure what happened. I started to receive Fatal Signal Caught for XymonLaunch.

I checked the xymonlaunch log and started seeing the following messages:

2017-11-16 19:10:15.609314 Task cid:image002.gif at 01D34FFA.21DA2880 terminated by signal 6 2017-11-16 19:10:15.609489 Task cid:image001.gif at 01D34FFA.21DA2880 terminated by signal 6 2017-11-16 19:10:15.609533 Task cid:image004.png at 01D34FFC.9E097850 terminated by signal 6 2017-11-16 19:10:15.609845 Task cid:image003.gif at 01D34FFA.21DA2880 terminated by signal 6

There were also core dumps in tmp directory.

Does anyone have any idea what is causing this?
