FMSA 11 is taking all available memory
I just moved the majority of my db's to a new FMSA 11 server running IWP from a FMSA 8 server that died. I noticed I wasn't getting the performance out of the new server that I was expecting, and was quite a bit more sluggish than the old one. After looking around I found that it was using all of the memory the server had, will processor utilization was in the low single digits.
64 bit Windows Server 2008 r2
Xeon Processor 8-cores
12 GB of memory
The server is about a year old, and had the new Network OS installed cleanly. It runs nothing else besides Symantec Endpoint Protection. In my opinion the server is slight overkill, but who am I to complain.
I do have a few very large files (in excess of 10 GB, much is due to a large amount of embedded PDF's), but rarely have more than 3 clients connected. I did not have this problem on the old server, which only had 2 GB of memory. The memory usage stays pegged out even if there are no client connections, or if I have closed all of the databases. The only way to get the memory usage down is to either restart the machine, or to stop/restart the filemaker service. Memory usage will climb slowly as it is running, or seems to peg out if the server runs a schedule like a backup or verification.
