Since several weeks I only use BT-module and had no crashes. The version I've installed is from ports, which is synced with the CVS version from 2006/11/21.

I compiled my last upgrades WITHOUT_THR_THREAD_MODEL.

As I haven't used the edonkey-module in the last time, I can't say if the crashes are gone forever now. I would propose to close this bug-report for now. I will try to reopen it, if this would be neccessary.

Greetings,
raXion

What happens when you compile MLDonkey without

WITH_THR_THREAD_MODEL="YES"

Is this bug still valid?
Did you ever test MLDonkey on a fresh install of FreeBSD?

I recompiled MLDonkey with the following options (hoping this  will produce better backtraces):

make WITHOUT_THR_THREAD_MODEL="YES" WITHOUT_GUI="YES" CONFIGURE_ARGS="--enable-debug --disable-pthread"

I did, and I also get core dumps ;-(.

What should I do now?

Did you ever try if libpthread produces the same core dump?

MLDonkey was made using the following command-line:

make clean && make WITH_THR_THREAD_MODEL="YES" WITHOUT_GUI="YES" CONFIGURE_ARGS="--enable-debug --enable-checks"

Should I avoid WITH_THR_THREAD_MODEL="YES" (which results in using libthr and not libpthread) and use WITHOUT_THR_THREAD_MODEL="YES" instead?

I used gdb with the generated core-file 'gdb -c mlnet-real.core /usr/local/bin/mlnet-real':

(How can I determine to which port the libraries at the beginning of the bakctrace belong?)

I still have random core dumps of mldonkey.

Right now I'm using FreeBSD-6.0-RELEASE and MLDonkey 2.7.3.

I will try to debug MLD using gdb (I have compiled it with "--enable-debug").

Does that patch print out the function backtrace when the application does an segv? The only thing you need to do is add b to that env. variabl?

I guess it would be easier to just use gdb, as you don't need to patch ocaml for this. This should work exactly like you would debug any other C code that does an segv. I'm not sure, but i guess the needed debug-symbols are already in the binary when compiled with --enable-debug .

Thanks.
I will try to patch OCAML, in the way sprialvoice' link proposes and test it with MLD 2.6.0. It's there. Greetings!

Maybe I can provide more info after that.

You could try to use gdb on mldonkey (and try to get an backtace), but i can't tell you from my head how to do that. Perhaps someone else can say how to exactly do that. Otherwise i will try, when i have time for mldonkey again.

I guess you did it the right way. It seems it is not possible to get an backtrace from an segv-ing application in that way. Perhaps the segv occurs in some c-code and not in the ocaml part? I hope someone else has some more insight how to procede here.

After crashing I can only kill the debugger to get out. It makes no difference wheter I enter 'y' or 'n' in the debugger after crash: I only get the same question every time. (See the end of my last post.)

Did I call 'ocamldebug' the right way?

I started wit ocamldebug and it seems to work. Only your option "printf '-l %p'" doesn't work. Is this critical for debugging? Here's the output I got:

You get mlnet.byte by the following command after you did run configure:
make mlnet.byte

Get an backtrace: Just type in "bt" in the debugger and then for each number after # type in "frame NUM" (replace NUM). Output looks similar to the example given.

Where did I find mlnet.byte?
After running 'find / -name "*.byte"' I only got:
/root/mldonkey-core-devel/work/mldonkey-2.5.30.15/ocamlpp.byte

/root/mldonkey-core-devel/ is my very own copy of
/usr/ports/mldonkey-core-devel.

Your last part "What to do after crash" didn't say anything to me ;-(( Maybe you can repeat this.

raXion <raXion>
Fri 03 Jun 2005 02:49:42 PM UTC, comment #26: 

copy mlnet.byte to your mldonkey directory and cd into it
execute the debugger as follows and replace "/path/to/src/" with the path to the directory src in the mldonkey sources:
ocamldebug $(find /path/to/src/ -name '.*' -prune -o -name 'gtk' -prune -o -name 'gtk2' -prune -o -name 'applets' -prune -o -type d -printf '-I %p ') ./mlnet.byte

then type the following in the debugger:
set checkpoints off
run

then wait until the problem occurs and type the following (however i don't know if the debugger will just be killed, like mlnet.) (if mlnet didn't halt into the debugger interrupt it with ctrl-c.):
bt

then for each # greater than 0 type (and replace # with the number):
frame #

example for the last part:
(ocd) bt
#0 Pc : 6160 Test char 22
#1 Pc : 6160 Test char 22
#2 Pc : 6160 Test char 22
(ocd) frame 1
#1 Pc : 6160 Test char 22
2 <|b|>test ()
(ocd) frame 2
#2 Pc : 6160 Test char 22
2 <|b|>test ()

Here's my output of make.

Could you tell us the output of buildinfo ?
From what networks do you have downloads running?

If none of these are likely to show why that happens, I guess you could use --enable-debug (that compiles in debug symbols) and run an bytecode mldonkey in the debugger. Perhaps we are then able to see where the segmentation fault happens.

Please check whether MLDonkey uses too much RAM and dies when no free RAM is available anymore. What networks are enabled and used? Some of them have known memory leaks (Gnutella for example), take a look at the other bug reports.

I will try memtest86 from boot CD later.
