Thanks, yes, {current_function, {gen, do_call, 4}} is always the same. I'll try to dbg and report here if something pops up.

I couldn't dbg somehow, I tried to erl -remsh to my app and open trace port, but got error: ``` dbg:tracer(port, dbg:trace_port(ip, 50000)). ** exception error: undefined function dbg:trace_port/2 ```...
