I am running BM 3.8 sp5 / IR 1

I am continually getting cache allocation out of available memory issues
between 7-10 days of running until the server eventaully does not respond.

I have 2 boxes setup exactly the same way and both are doing the same,
despite one experiencing considerably less load.

I have been examing the following stats and wondering if someone can
comment:

Server 1:
Long term cache hits: 95%
long term cache dirty hits: 0%
LRU sitting time: 10:23:45:23

Server up time: 10:23:45:23



Server 2:
Long term cache hits: 91%
long term cache dirty hits: 0%
LRU sitting time: 1:23:43:37.7

Server up time: 14:22:37:09


Server 1 experiences more load.


can anyone explain these stats, I have other servers where cache hits
are 0% and they seem to stay up for long times.

Any ideas ?
