Re: Help: UnmarshalException running Jini

Yes I can change the code and I'll try put an exception block on the method.
I think I've pseudo-fixed the problem by serializing some other classes
which I didn't earlier because it didn't seem like I needed to. However, I
still occasionally see the same error posted earlier. 

Another question if I may. I keep getting a java.lang.OutofMemory error when
I attempt to run large number of tasks, which isn't actually that large
considering I'm running them on a 64-node dual processor cluster with 4GB
mem each (max heap size is set to over 3GB). The mem and load monitor on the
cluster didn't show any signs of heavy utilization either. Hence, the
question is if there is actually a prescribed memory limit on a JavaSpace
when one creates it? My main Javaspace is created on an independent node
with 4GB mem and barely use 15% mem when the error occurs. Thx.
