Please show me the output from the following commands on the affected machine:
echo "::svc_pool nlm" | mdb -k echo "::stacks -m klmmod" | mdb -k Then run the following command: snoop -o snoop.out rpc nlockmgr Then reproduce the problem (to see the ENOLCK error) and then Ctrl+C the snoop. Make sure there is something in the snoop.out file and send the file to me. Thanks.
