I have a problem which causes a java.lang.OutOfMemoryError

Normally when I receive packets with no error I get the following log output:

[2014-01-17 17:25:21,217] [InputStreamThread] [INFO]

But sometimes I have the problem that RxTxSerial Com returns that no data is 
available:

After this I get a java java.lang.OutOfMemoryError Exception...

Has anyone an idea how to fix this?

How much memory have you allocated for the process? How much is it using?
