I cannot offer any help, but a few questions:
Are you running anything on the server (apart from Fb/RC2)?
Could you try Fb/1.0?
What is page size and cache size? 1GB RAM should be much more than a
single Fb database can use (10.000 pages of 8KB pages just makes about 80MB).
How much RAM is in use on the server? How much does Fb use? (Memory use as
seen by TaskManager may not be very accurate, but maybe close enough).
Can you pinpoint what your program is doing when this occurs?
