Hi,
We are noticing a few problems when running PVFS2 version pre1.3.1.
- pvfs2-client-core memory keeps increasing after using the system for
4-5 days. We have seen it go as high as 900M, at which time, we have to
kill it and remount the file system.
- The pvfs2 client log shows the following errors. The server does not
have any corresponding error.
[E 23:31:07.186802] *** msgpairarray_completion_fn: msgpair failed, no
retry: Connection reset by peer
[E 23:31:07.186856] Error: state machine using an invalid termination
path.
- We have also seen an error in the pvfs2-server log indicating the the
pvfs2-server ran out of max open file descriptors. I was unable to
capture the log message as the server clobbered the log (instead of
appending to it) when I restarted the pvfs2 server. The kernel
parameters for max open files are quite high.
- One pvfs2-server in group of 8 keeps running at 99.9% cpu.
Incidentally this is the same server which ran out of max open file
descriptors.
Has anyone seen these or similar errors? I would appreciate if anyone
can share their experience in resolving these errors.
thanks,
uday
