I think it's a Google App Engine (OutOfMemoryError on Jetty)
question.
After Selenium RC hits the Dev Mode url about 34 times, I get
previously mentioned error [ERROR] Out of memory; to increase the
amount of memory, use the -Xmx flag at startup (java -Xmx128M ...)
This happens with -Xmx1024M setting.
So is there a way to free up memory after connection is broken? When
Selenium breaks the connection, DevMode quits with the following
exception:
20:02:12.232 [ERROR] [myModule] Remote connection lost
com.google.gwt.dev.shell.BrowserChannel$RemoteDeathError: Remote

So does this cause a memory leak? Then after 34 of these, it finally
runs out of memory.
