<div style="margin-top: 5pt; margin-bottom: 5pt; ">I am trying to understand the following output from “lsof”.</div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">All/most of our compute nodes (pvfs2 clients) have the following output as reported by “lsof” </div>
<div style="margin-top: 5pt; margin-bottom: 5pt; ">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. </div>
