Hello: I am having an issue with cache buffers. I keep
getting an snmp alarm:

'Cache buffers fell below threshold of 40% on server ..."

I don't know if this is something to worry about or not.
The servers have 2GB RAM. One runs zfd7 and the other gw7.

I am not familiar with memory issues as I have not really
seen many. Can you help me out??

Thanks, Chris.
