We are running a DB2 client/server transaction processing application with around 200 users on a Window NT Token Ring network. When the DB2 server gets heavily loaded, the network seems to freeze. I have monitored a number of clients and the freeze seems to happen after the current DB access is complete. There is no obvious processing going on in the clients. After a period of a minutes, the network comes out of this state. The problem typically happens a couple of times a week.

Any ideas...
