We are already running with GC_free_space_divisor set to 20 in our GCJ build, as you suggested this the last time we were whacked by one of these memory allocation problems. But I am curious - can we expect unpleasant side-effects if we have this parameter set to the "extreme"? What do you thing about this? Is this parameter a subject for a tuning study, or are there some rules of thumb that can be used to guesstimate the best value?
The higher the divisor, the more often GC will run resulting in less
real work being done.
