amuled crashes after some time
« on: January 16, 2005, 11:54:54 AM »
I'm running amuled from CVS-tarball 20050115 compiled with wx-gtk2.5.3 on a Vector-Linux 4.3-system.
After some time amuled crashes.

bt output:

It's looks like memory corruption. I have crashes in random places, but valgrind doesn't complain. Which means in tern, that there's syncronization problem (lock missing).

Not always no. Valgrind sadly does not catch everything, so it could still easily be normal memory corruption.

So my memory is broken? Is there a way to fix this?

No, no. Don't worry, it's not your memory that is broken, it's aMule doing odd things with it. Problems like this generally result in crashes like yours, and the term for that is simply memory-corruption which refers to the fact that the memory values used by aMule were corrupted due to a bug in aMule. So this is something we should worry about, not you.  ;)

Meh, we need thread-safety in more classes ... I've added it to CIPfilter and I guess I'll start adding it to other classes as well now ...

Both crashes coming from UDP socket thread. I will check locking there

lfroen: what about a test with disabled udp?

Lenni if you want you can checnge in prefs the usage of UDP in amule,
in your .eMule set
UDPDisable=0
to 1 and try it

maybe it works, maybe it does not.

I set UDPDisabled=1 but amuled crashed even more often  ?(
So I upgraded to today's CVS and will see...

stefanero: I'm not sure what exactly "disabled UDP" does. Does it mean that socket is not created ? Or amule doesn't SEND udp packets ?

the 1st udp port is not creaded.... 4672
thats what it does, I think some udp packages still go over the 2nd udp port tcp+3

I'm running CVS20050118, with UDPDisabled=1, for over 14hours now  :D
With UDPDisabled=0 it crashed after a short time (after using up all CPU-resources that was left).
