I removed all distribution wx packages and rebuilt.  I am certain aMule uses wx 2.8.12 which I compile myself.  It is also verified with ldd.

There were three crashes in one evening and one over the nighttime.  I checked bt each time and all have the usual pattern with segv just after

Code: [Select]

_GSocket_GDK_Input (data=0x2db1b90, source=45, condition=GDK_INPUT_WRITE) at ./src/gtk/gsockgtk.cpp:43

By the way, this is difficult to fix right now because wx 2.9 had a rewrite of sockets code, so I'm waiting until wx can be built against gtk head to start writing patches.

It is understandable that you must wait to attack the bug.  External dependencies force such things.

Can crash probability be decreased by restricting total connection count?  I think of disabling kad, reducing maximum connection count in preferences, etc.  Else is it only the number of uploads and downloads at each instant that matters?  I understand it may be a guess! 

Well kristof, you may try to reduce the number of active downloads/uploads. That is, start pausing files until amule stop crashing. Once you manage that, it would be helpful to know what the limit is, so I'll try to reproduce.

Well kristof, you may try to reduce the number of active downloads/uploads. That is, start pausing files until amule stop crashing. Once you manage that, it would be helpful to know what the limit is, so I'll try to reproduce.

I will do that.  However, I can give an upper limit start.  With the following I crash aMule in 1-2 hours:

kad enabled
max simultaneousness connections 250
max new connections / 5 seconds 25
downloads 800
upload limit 64KB/second
download 150KB/second
slot allocation 4KB/sec

Overwhelming majority of files have few/slow/no sources.  Only 10-15 maximum can be seen to actively download at one time. Usually it is less than 10.

I also reported a high cpu use bug in this thread http://forum.amule.org/index.php?topic=18867.0  I don't know if these are related.  High cpu does not always happen.  Socket bug always happens.

It seems that disabling kad helps runtime but I have not yet kept records well enough to support my feeling.

[Stu Redman]

I'd rather try limiting the number of connections than pause downloads.

[kristof]

I'd rather try limiting the number of connections than pause downloads.

In Preferences / Connection / Max simultaneous connections ?

[Stu Redman]

Yes.

[kristof]

Latest trial:

kad disabled
max simultaneousness connections 100
max new connections / 5 seconds 25
downloads 800 (about 150 are stopped state)
upload limit 64KB/second
download 150KB/second
slot allocation 4KB/sec

aMule ran just less than 24 hours.

kristof, you could try running amule under gdb, maybe the backtrace will help.

[kristof]

Lately, I always run amule under gdb.  I look at backtraces after every crash but I have stopped saving them because they all look the same.  It is always a segv in _GSocket_GDK_Input.  The backtrace of the offending thread is always the same.  I included below one of the last that I saved.

I can post all backtraces for future crashes if it is worthwhile.  I did not want to flood the thread with redundant information.

To be more exact it is always line 43 of gsockgtk.cpp.

Ok Kristof, that backtrace is what we expected. Just one thing, could you install debug packages libgtk2.0-0-dbg libx11-6-dbg libstdc++6-4.4-dbg libc6-dbg and get the backtrace again?

Ok, installed.  I will post new backtraces once aMule crashes.

[kristof]

Here is the latest crash.  Maximum connections set at 75 with kad enabled.  It was a few hours before aMule crashed.

I first ran aMule with maximum connections set at 50.  aMule ran for days with no problem.   I enabled kad and it did not crash.  I lost patience so I changed maximum connections to 75.  aMule ran more than 24 hours.  The end began with high cpu as I have reported in another thread, 160-180% of dual core.  aMule used a large amount of memory, 1.1GB resident.  aMule took more and more memory.  The machine swapped continually.  aMule gui froze.  aMule continued to eat memory.  aMule was killed because of OOM at 4GB of memory used.  No bt from OOM.     I had to restart aMule to get the bt above.  Luckily (?) it happened in some hours.

[kristof]

Is this bug one that we might find to be fixed in 2.3.1 RC2?  I don't mean to pester.  I am asking only so I know whether to bother compiling the new version. 

[Stu Redman]

I'm afraid no.
