Are There Known Problems With tkinter And VPS Servers?

[Tim Daneliuk]

I am the author of https://www.tundraware.com/Software/twander, a cross platform, macro-
programmable file manager written in python/tkinter.

Of late, I am seeing core dumps of this program (which has been stable/mature for some
years) but only on VPS servers, both FreeBSD 10 and CentOS 6/7.

Is there are know problem here and/or can anyone suggest and approach to isolate the 
fault?

Thanks
