Message 43203 - Posted: 5 Jul 2007, 7:30:07 UTC

I'm getting nothing but client errors (127) from one of my machines. The machine that's having problems is 300MHz, 128MB RAM. My other (better) machines do not have this problem. I'm using the Linux version of BOINC/Rosetta. What does an exit status of 127 mean? How can I fix this?

Here's an example result page:

The answer may perhaps be found in the system requirements.

yep hes right, you need a minimum of 256MB to run RAH anything else results in errors.

Not to mention the fact is it worth running on a pentium II? 4creds per WU, is it even worth the electricity. Maybe investment in even a £250 ($500) machine would result in a 10 fold increase in power.

127 errors are missing file/library errors. From a terminal CD into your Rossetta project directory and run ldd on the rosetta executable. Check the output for missing libraries. You'll then need to track down your distros packages that contain these libraries and install them. If you need this explained further just yell :)

Cheers

p2? ohhhh...time for a bit of a update. might as well get a different box.
i am doing ok with a amd cpu that was medium level of its kind of processor type,with 512mb of memory. so yes, perhaps a small upgrade of the cpu and bit more memory would be beneficial to your quest of crunching and getting some sort of reasonable credit.

Ah-hah! Thanks for the info and instructions, but when I run ldd on BOINC/projects/boinc.bakerlab.org_rosetta/rosetta_5.68_i686-pc-linux-gnu, I get "not a dynamic executable" as the output.

Looking at your results you occassionally complete one or two wu's, then you have a string of errors, and the errors have changed from 193 to 127.

It could be that your box is flaky, or maybe the small amount of memory is causing the command not found error. Is this box stable on any other project, and how big is the swap partition? Also what distro are you running?

I never tried the 300MHz box on another project. The 300MHz box's swap is 500MB. I was using the Ubuntu 7.04 distro. Well, I cannibalized the 300MHz box for parts for a newer 533MHz box, and that new box doesn't seem to have any problems. I might try to use the 300MHz box later as a diskless node. Thanks for your help.
