OutOfMemoryError when opening environment using Java API

Question

I've been getting a strange error recently and I can't seem to figure out why. Whenever my DBXML environment gets opened, I receive a "java.lang.OutOfMemoryError: Cannot allocate memory" error. The machine has over 700 MB of free RAM. Here is the code I use to create/open the environment.
EnvironmentConfig envConf = new EnvironmentConfig();
envConf.setAllowCreate(true); // If the environment does not exits, create it.
envConf.setInitializeCache(true); // Turn on the shared memory region.
envConf.setInitializeLocking(true); // Turn on the locking subsystem.
envConf.setInitializeLogging(true); // Turn on the logging subsystem.
envConf.setTransactional(true); // Turn on the transactional subsystem.
envConf.setThreaded(true); //Turn on thread-safe
envConf.setLogRegionSize(500000); //Increase logging region
envConf.setErrorStream(System.err); //Set error stream
envConf.setMaxLocks(5000); //Set max # of locks
envConf.setMaxLockers(5000); //Set max # of lockers
envConf.setMaxLockObjects(5000); //Set max # of lock objects
envConf.setMaxMutexes(10);
//Set the error stream to write to a log file
String fileName = SystemProps.DATA_HOME + "/dbxml.log";
File f = new File(fileName);
FileOutputStream fos = new FileOutputStream(f);
envConf.setErrorStream(fos);
return new Environment(envHome, envConf);
Is there something specific I'm doing here that would require lots of RAM? Could it be related to the size/contents of my DBXML containers?
Thanks in advance.

I'm not exactly sure why this worked, but running recovery seems to have fixed my problem.
