DLM/OPS latch waits

Thanks for all your help on this one, guys.

I think it was my udp_sendspace being set too small (smaller than DBMS block size) that was boinking me.

Anyone out there have a udp_sendspace set to SMALLER than their OPS dbms block size?

hope not, cuz it would mean I am vomiting up the wrong totem pole.

(something funny about that metaphor)

in my 816/Tru64 4.0f instance, I have alot of latch waits/sleeps/longholds on:

dlm resource table freelist
dlm lock table freelist

I have downloaded Note 72316.1, but this does not contain material exactly on these
latches.

Further, I have very very high system-level waits for:

"lock manager wait for remote message"

Questions:

1. If I wait for these latches, what exactly is happening in the kernel? in the OS?
2. What does the system wait event refer to, exactly?
3. What can i do to release pressure on these latches?

thanks.....
