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?

Category:  Core
Severity:  7 - Major
Item Group:  Program malfunction
Resolution:  None
Assigned to:  None
Status:  Open
Release:  2-5-18
Release:  started in 2.5.12
Platform Version:  Linux
Binaries Origin:  Downloaded from third-party page
CPU type:  Intel x86


Summary:  one cpu spikes to 99% after 10 hours.

Original Submission:  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.

The data loss should be repaired in current CVS versions:
2004/05/02: Fabrice
  - Fixed bug causing lost of partially downloaded chunks.

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.
