This is the problem.

That's an unusual and discourages syntax for the -Xmx command.  Use a
value in megabytes appended by m, e.g. -Xmx512m for 512MB max heap.

It would be helpful to benchmark your app in order to determine how much
memory it requires.  Figure out the expected max load on your app.  Use
a stress test tool like JMeter to simulate this load.  Keep increasing
-Xmx until you no longer get OutOfMemoryErrors under the max expected
