[SR-Users] core generated - 502 Bad gateway

[Daniel-Constantin Mierla]

Hello,

the backtrace you got is not relevant, because it is from the main 
process that is handling the singnal of the child process that crashed. 
So the corefile from crashed process has been overwritten.

Can you enable one core file per process and try to reproduce? Then get 
the backtrace from each core generated.

Cheers,
Daniel
