Some more info, m_abyPartStatus seems to be trash. I have searched the code, and every delete has an assignment with NULL in the next line, so it should not be a dealocated pointer. Something seems to be leaking...

Cheers,

Marcelo.

A similar one, but not exactly the same. Same problem with m_abyPartStatus:

jap, I think you are right...

Except the crashes happening when I view all sorces of a file there are only crashes related to

mem_alloc (optional with Seg fault)

*Part* Functions as Phoenix trace but veen more different functions

[phoenix]

Ok, more info. I have reduced the number of active downloads. In the previous traces, I had 27 files downloading simultaneously. Now I have 13 active, 5 downloading, 8 waiting. amule is up for 8h:34min, and in this machine it's a record. The problem seems to be related to the number of active downloads.

I believe there's something leaking, and the number of downloads only makes it more evident. I think I'm going to play a little with the code to proove it.

Cheers!

"I believe there's something leaking, and the number of downloads only makes it more evident. I think I'm going to play a little with the code to proove it." <- DO IT, DO IT!!! FIX IT!!! xD

If you get any good results, don't forget the aMule team exists and is waiting for any fix ;-) (You can post on the Patches forum).
Greetings and thanx!

well I have 3 amules running on 3 machines simultanously for my little estings and on one machine there are only 12 files waiting, all short before completion (9,28 or 18,55 Megs to finish) and even there amule always crashes with SEG fault at least every two hours. Its not very funny to have 12 files open since months which just don't complete because amule is crashing before you get a good position in queue

On another machne there are 120 downloads active and it runs a stable as the machine with twelve... crashing at least after two hours with SEG fault and pointing at a *Part*-Function (5 or 6 different Functions I have seen untill now)

[Kry]

(one of those special times when kry comes around and post instead of only reading)

phoenix, you seem a great bug-tracer and so I'm asking you to join the official testers team and get to test cvs snapshots of current development.

[phoenix]

Kry, that would be great! What shall I do?

[phoenix]

Ok, what I suspected is in fact, true. I was examining the core file from the last trace, and something is definetly leaking. I have created two varables, one before and one after m_abyPartStatus. The first one is called must_b_aa, and the last one is called must_be_55, and they are initialized at the constructors and nowhere else are touched. And guess what? must_be_aa is 0x43 and must_be_55 is 0x94

[phoenix]

Would that make sense?

I have recently found that GetNext has a side effect on pos. I used to think that this was ugly :-) Is this a new trend? :-) Anyway, it took me some time to figure it out, I don't think that this is good for readability. An ampersand in front of pos does not take that much space in the source.

Anyway, in another part of the code (PartFile.cpp:1674), just beeing paranoid, I changed

Code: [Select]

for(POSITION pos = m_downloadingSourcesList.GetHeadPosition();pos!=0;)

to

Code: [Select]

  for (POSITION pos = m_downloadingSourcesList.GetHeadPosition(); pos != 0; pos = m_downloadingSourcesList.NextAt(pos)) {

The correct value of pos after the attribution should have been 0xa1c5a18, but it segfaulted with 0x18, as if it only got the last byte from the pointer. I have read the code many times, but did not find a suitable explanation. Maybe a stack corruption?

By the way, I have the core open in gdb, if anyone is insterested in the value of some variable.

Cheers!
