V3.0.5 on CentOS 7.6

Is there any known issues with TG v3.0.5 running on CentOS 7.6? I keep getting the segmentation fault like below. Any suggestion on how I go about debugging this?

This is not the response you are looking for…

I am running (a variation of dev and enterprise editions of) 2.5.x, 2.6.x, 3.0, 3.0.5 and since last week 3.1 on CentOS 7.8 for 1+ year by now without issues. Plain OS installation, no customisation or guru customisation, although I keep it up-to-date.

OK. The issues I am seeing are unique to what I am doing then. I have very complex UDFs that require quite a few external libraries linked for them to work. Maybe some of the libraries are conflicting with what TG requires. I will upgrade to 3.1 and keep digging. Thanks!

Cheers,
Jim
