I just recently switched my machine over to Fedora Core 4, have tried all the tips and tricks here, but still, every one of my units is erroring out the same way, and all seem right around midnight when I'm asleep.

Machine Descriptions:
AthlonXP 2400+
80 Gb HDD, 85% Free space
1gb Memory
FC4 Linux with all the latest updates

Boinc-
Rosetta-400%
Ralph-400%
Predictor-200%
Simap-200%
SZTAKI-100%
LHC-100%
Seti-100%
Einstein-100%

General Prefs:
Do work while on batteries=no
Do work while computer is in use=yes
Leave app in memory=yes
Switch app=every 120 minutes (2 hrs)
Use no more than 40Gb disk space
Leave at least .5Gb free disk space
Use no more than 50% disk space

Boinc output is directed to a file named messages, I can provide this file if needed.

When running rosetta under WindowsXP, I had none of these probs, and reading these forums, I see Linux/UNIX clients are have nothing but trouble, sounding like the code is not to sound. Ralph units, and others, are running fine, just the Rosetta units are rife with errors it is looking like. I can, if so necessary, boot XP up into a VMWare window and run the Boinc software from there, but I am not wanting to place that much overhead on this machine, just to crunch a Rosetta unit when all other projects are doing fine under Linux. Looking at the Boinc Wiki, error 131 is dealing with file size to large or disk space exceeded????, if I'm not mistaken. What is going on to fix this under the Linux/Unix clients?

Would you mind passing your error logs along to us, along w/ your WU # and machine #. It would be a help to us. Thanks

Yes, your error logs would be helpful.. It's likely that some of the SELINUX protections are preventing communications between these processes. You might try a :: fixfiles relabel (Don't remove /tmp/ files when it asks)...

on your system and see if that helps...

you should also read the man pages on the command :: setsebool

There are a couple of dozen boolean based protections in the directory:: /selinux/booleans

You might try setting some of these on and off to see if your errors relax a bit. You might also try turning the SELINUX protections off... :: echo "0" > /selinux/enforce will do this... don't forget to set it back to "1" after you are done experimenting..

Hope this helps...
