Hi Amit,
What version of PVFS is this?
What does the output of netstat -tan look like?
Thanks,
Rob

Hello All,
I am trying to understand the following output from “lsof”.
All/most of our compute nodes (pvfs2 clients) have the following
output as reported by “lsof”
Few of the pvfs2-client nodes have greater than 1024 open sockets
for just the pvfs2-client process. Current ulimit for maximum number
of open files per process is set to 1024 on all of our computer
nodes. I see this as a potential performance problem. I was
wondering if any of you can help me interpret the output and fix any
issues that this could be causing.
