As this bug seems to be hardware related it is closed.

two things happened.  i changed to another machine (almost identical - p2 300 (x2) with 320MB ram, same model MB but this one's bios chip isn't dead),  and i started using the 2.5.20 spiralvoice core.

good news and bad news.

bad news is that i can't get the strace for you.

good news is that i can't get the strace because the thing won't die.  In addition to that it's faster than ever...  i've had to go looking for stuff to download just to keep it busy!

if it crashes i'll follow up with an strace first thing, but i'm keeping my fingers crossed.  -it's been running for 15 hours and downloaded close to 1GB of files.  i put the machine under heavy load, and put the local network under heavy load.  the net connection even went out for a little while-  no problems yet!!

I quickly looked at the logfiles but could not see something obvious. Could you send a strace log of the mlnet process when it blocks the CPU? Maybe this problem is SMP-related?

The data loss should be repaired in current CVS versions:

one more thing i just noticed (aside from the fact that i left the post as a "Compilation problem" when it is obviously not).

when i restarted the core i had lost considerable data on two of the 4 downloading files.  roughly 10MB on one and about 60MB on another. (at least it restarts now though)

the other two files seemed the same.

sorry, i had forgot to login... stupid...

also, forgot to mention that with the 2.5.16f and 2.5.16k cores after this problem happened once i could no longer even start the core again without it doing the same thing right away.  With 2.5.18 however i can start it up again without trouble.  so, at least that's something.

dual P2 266 machine with 256MB ram.

I started having this problem around 2.5.12.  i have tried SpiralVoice's cores as well as building my own cvs cores.  all give the same results.  this last time i used the 2.5-18 core from Spiralvoice's page and I had disabled all networks except eDonkey some 7 hours before it crashed.

everything seems to run fine and downloads are fast, but after about 10 hours of running, mlnet cpu useage will spike to 99% and i can no longer log into the core.  I have to kill-9 it.

i have made the buginfo and included the logfile in the archive (mld.log.crash).  i can get more info if required and i'm more than happy to help any way i can.

I've toyed with various options settings, but, like i said, everything else seems to be fine (mem useage, etc...).  and i have trouble figureing out exactly when it's going to crash.
