NFS locking up on reads and writes

NFS has just started consistently locking up over the last week. It will be fine for the first 10-15 minutes but then starts to take longer for reads and writes and eventually quits responding at all. Are there log files I can look at to help me determine where the problem may be.

I am running Centos 5.6 in VMWare ESXi 4.1 connecting to the DSS through NFS.

Let me know if I need to provide more information.

Thanks in advance.

I have also noticed I get empty files when I download my UID and GID settings.

Please open support ticket via user portal to receive small update for Uid/Gid and send us logs from DSS to investigate NFS issue.
