My guess is that the server have less than 3 GB of memory? I think the =
difference is that an app on Java 1.5 32 bits will use 64 GB of memory =
max unless you change those values, but with Java 1.6, the maximum value =
is 1.5 GB, so if the server don't have memory, yeah it can fill out =
memory and the system might start swapping like a mad man, and good luck =
trying to access the server when heavy swapping is happening.

Before trying to use Java 1.5, you should use the -Xmx parameter to =
limit the number of RAM the app can use.

Is this a OS X server?=
