If you're getting timeouts with TCP, that usually indicates you've got networking problems. Do other applications that use TCP show the same behavior? netperf? ftp? rcp? Does lanadmin report any problems? Does the switch report any duplex mismatches?

Dave,

Plesae see attachment. There seem to be excessive broadcasts and the switch is reporting that the interface has been up and down.

I am not physically at the data center, is there anything else i can check on the HPUX side?

Thanks!

Dave,

The backup started going, finally after a while..

This is a oracle backup through Netbackup. It took a while before it started. We are good to go.. i dont know why the switch (HP Procurve 5406zl) reports interface being up and down.. i have to catch hold of switching folks.. :-)

I am glad this started working... backup is going on now.. !

Dave, i really appreciate your time and help with the case. I downloaded your NFS troubleshooting PDF (great Doc)..

Thanks a ton!
