Re: JAVA USED 95% OF THE GC HEAP.

[Jim Oberholtzer <midrangel@xxxxxxxxxx>]

The server can become overwhelmed by the garbage collection and all but 
become unresponsive.  Check and see how often garbage collection is 
running.  If it is more than several times an hour than you may need to 
increase the size of the heap.  262144 seems really small to me for any 
server with applications actually running.
