Using python3.6 now.
I've also used the 'handle SIGPIPE nostop noprint' to skip SIGPIPE.

Now the interpreter is killed instead:

INF  2019-02-13 15:42:19,131 web:2162 log_request - 200 GET /NPM.html (10.0.6.209) 1.10ms

Program terminated with signal SIGKILL, Killed.
The program no longer exists.
(gdb) bt
No stack.

And the dmesg shows, what I think is the real reason, for python3.5/3.6 dying on me (out of memory):
