I think you should rather use ZEO than raise number of threads to such a
big value. Also there are some rules about pool-size. I don't remember
exactly but seems to me that it is too small, but
in general I suppose it has nothing to do with your problem...

Situation you're seeing may appear if there is something that blocks
all your threads, like all threads are waiting for RDBMS response...
