Getting these errors in my FFS logs (multiple FFS batch jobs reporting these errors - jobs have worked successfully for years on this computer).

I have plenty of free memory in the computer.

Has FFS corrupted perhaps?

I've seen bad memory cause these errors system-wide

Rebooted my PC last night, so far this error hasn't appeared. Hopefully that's cleared the problem, otherwise I'll run some extensive low level memory tests (although I suspect the memory is fine as nothing else in the PC is reporting any issues).

As a follow up question: is there a way to increase the amount of memory allocated to the FFS exe's?

No, that would be an OS limitation. The FFS manual estimates 1.7 million item pairs for 1GB of memory. If you are on 64-bit, allocation is not an issue. If you are on 32-bit OS and have 3.4 million pairs+, then get 64-bit.

Yep I'm on 64-bit. Since the recent reboot, I haven't seen this error occurring again, so tentatively I would that was the solution.
