<P><FONT SIZE=2 FACE="Arial">Folks,</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">I ask here in anticipation that somebody out there in cluster-land has run across this limitation and can advise me on moving past it...</FONT></P>
<P><FONT SIZE=2 FACE="Arial">We are looking at an application which uses a proprietary license manager. The client connects to the license manager at start time and (according lsof on the system running the license manager) seems to hold a socket open during the duration of the job.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">We want to run a couple of hundred of these jobs on our cluster, but after job 126 the client can no longer connect to the license manager. The server hosting the license manager is otherwise fine, and you can continue to perform network-based operations on and against it...</FONT></P>
<P><FONT SIZE=2 FACE="Arial">The vendor feels that they have not coded a specific limit; I'm wondering if it's file descriptors or somesuch. I raised the limit of FDs on the system to 65000+ and verified that the change took effect; no change to the applications behaviour. It's a c-based app, compiled with gcc on a Fedora Core 6 system, I believe.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Any thoughts?</FONT>
