Title: amuled crashes after some time
Post by: Lenni 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).

Title: Re: amuled crashes after some time
Post by: Xaignar on January 16, 2005, 12:54:31 PM

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

Title: Re: amuled crashes after some time
Post by: Lenni on January 16, 2005, 12:57:19 PM

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

Title: Re: amuled crashes after some time
Post by: Xaignar on January 16, 2005, 01:37:28 PM

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.  ;)

Locking problem. is the same kind of prob I fixed some days ago with sorting, guys...

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

Can someone please post here when the problem is solved and I can download a new CVS? Thanks!

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.

Title: Re: amuled crashes after some time
Post by: Lenni on January 18, 2005, 10:44:40 AM

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

Lenni

Title: Re: amuled crashes after some time
Post by: lfroen on January 18, 2005, 10:48:21 AM

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 ?

Title: Re: amuled crashes after some time
Post by: stefanero on January 18, 2005, 10:57:47 AM

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

Title: Re: amuled crashes after some time
Post by: Lenni on January 19, 2005, 10:46:50 AM

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).

sounds like it works betten with udp disabled? nice...
yesterday I manages 6h but then gdb crashed  8o

keep is informed please what you get for best uptime ;) I am curious :)

lol

good to know ;)
disabled UDP makes sources finding a little slower, thats about it....

Title: Re: amuled crashes after some time
Post by: Lenni on January 21, 2005, 04:21:18 PM

Is it possible that disabling the UDP-port is increasing CPU-usage?
I had a usage of 20-30% before, now it's about 50-60% on a Celeron 400 MHz.

Title: Re: amuled crashes after some time
Post by: phoenix on January 21, 2005, 04:37:02 PM

Lenni,

Should be the opposite, disabling UDP should decrease you CPU and bandwidth usage, if you can feel any difference.

Btw, if you use a recent tarball, please enable UDP, i think i have fixed the crash and it would be nice if you could test. ;)

Cheers!

Amuled crashed after 4 1/2 hours with UDP-port enabled.  ;( With UDPDisabled=1 it's running for 10 hours yet.
edit: using CVS20050121 now.
