Hi Christina,

Sometimes job timeouts are due to timeout values being set too low for the particular system, especially with older setups. You can try to increase the timeouts in the fs.conf (ClientJobFlowTImeoutSecs), it usually defaults to 300 (5 minutes). It may also be that there are failures on the servers and they're not returning responses back to the client. Do you see any messages in the server logs? Can you verify that the servers are still running after seeing this error?

Hi Everybody,

I have been facing some problems recently when using mpich2 and pvfs2.
My program worked fine earlier and I did not face any problems before
while executing those programs. All of a sudden, when I run my
programs now on a reconfigured setup (8 IO servers, 8 clients and 4
metadata servers), I get the below error messages. I have browsed
through the forums and there have been similar reports before.
However, I couldn't really figure out if anybody got a solution to the
problem. I generally get the error when I scale the number of
instances running to 16 or 32.
