dependingon some OS factors that we don't entirely know. I'd never recommend going above 100-150. With no more than 2Gb

My guess is that Windows is running out of handles. Each backend uses about
150 handles. 100 Backends means 15000 handles. Depending how many other
programs are currently running the no. of startable backends will vary
depending on the total handle limit Windows imposes.
