We are running on NetWare 6.5 SP1a, clustered with two nodes, the server
memory is 1024MB each. The server memory will reduce (leak) to out of
available cache memory and caused server hang after few months. The error
message is "out of available cache memory"

Please advise other than upgrade the service pack to SP2, any other
workarounds for memory issue?
what is the ideal server memory? 2Gb for each of the server?

Thank you
Best Rgds
