I've experienced slowdowns due to reaching heap space limits. Check on the process memory use. Sometimes jvisualvm from the JDK1.6 is real good help to check memory use and for thread dumps.
When an OutOfMemory exception happens in Java, it may kill important threads in an application and things start to hog. Even locks may not be released forever. My 2c, hope it might help.
