I used all my quota this month and my ISP throttled connection to 512/512.
That's when amule begin to crash -- it works for less than an hour until
"Segmentation fault". I have only KAD enabled and I have a feeling that it may
be related to number of simultaneous connections (although lowering max
simultaneous connections from 900 to 90 did not help). No errors are logged to
console and I tried to run amule under GDB for a while but under GDB it is
slow and problem do not manifest. Without GDB it crashes in 30...60 min.

I think on fast connection I've seen few occasional segfaults in the past but
it was not unusual for amule to last for days and even weeks while now I have
an hour at most.

This is on up-to-date Jessie.

I'm out of ideas how to troubleshoot further...

Hi!

I think that the only way to report it upstream for a fix is to let it
run under gdb and wait for it to crash and then generate the required
tracebacks.

I have an instance of amule running from more than 1week and it is the
same version you are reporting this bug againts.

Just a note: Jessie doesnt include amule, as it was not possible to
port it to WX3.0

So it is not a known bug...
Thanks, I'll run it in GDB and try to wait long enough for it to crash.

It was the same for me until ISP began to throttle my connection...

Of course. I'm reporting from another machine so at least I had to mention
what is running if I'm not providing list of packages as generated by
reportbug...

no well maybe it is known but just mention it SIGSEGV without proving
even a location memory or so it is hard to say if someone else already
spotted it or now

thanks a lot!!

aaah I now I see what you mean with that.

Cheers,

I'm sorry, the way upstream wants backtraces is running these gdb commands:

bt
bt full
thread apply all bt

Can you please retake it with the output of all the 3 commands (I will
have to write a guide to include into the package about taking
tracebacks as upstream wants)
