NewGen switches are odd. I am not sure about the NewGen configured with -Xmn100m and also -XX:NewSize=48m both switches are for configuring NewGen however set to differing sizes. Perhaps the java heap error is related to this remembering that Heap is made up of NewGen and OldGen or YoungGen and Tenure (if you like those name conventions instead)?
Suggest loose one or the other NewGen setting from JVM arg and see if java heap errors cease. Logging is always are good idea rather than just guessing at the problem. I do not mind the low pause collector in combination with the newgen collector. HTH, Carl. >Wil, > >I rather like the low pause collector combined with the UseParNewGC.
