Mem Use was over 1Gb for fbserver.exe process
Server OS is Windows Server 2003
It has 2Gb RAM with 2062Mb of virual memory
At the bottom of task manager at the time, the Commit Charge was 50%, ie.
about <2Gb / 3959M
Since I have stopped monitoring the fbserver.exe process has not exceeded
241Mb (peak Mem Usage) and Mem Usage if frequently about 80Mb.
