I upgraded all Nw6.5 servers in the tree to sp4a. 3 servers are now having
memory problems. I am using one server as a test to step through
TID10091980 but I have gone through all 6 steps and I'm still having the
problems. After 6 days of uptime, the server starts with the errors and bad
things start to happen.

I would think steps 4 (Set the File Cache Maximum Size parameter) and steps
5 (Set a hard limit on the amount of RAM that NSS can have) are the most
effective but it specifically states that if you have sp4 or above you
should not set limits.

So what's the next step?
