Question

We have a java program running in linux. The problem with this program is that it's memory usage keep increasing in size and does not stop. Eventually all the swap space will be used and the system dies. However, here is the key, the heap usage DOES NOT INCREASE. We cannot figure this out. What could the problem here?
Heap Usage shown by profile: cycles between 450-500Mb. VM was set to havea 600Mb limit
Total memory usage 6Gb shown by the unix utility top and growing.

I'm sorry we can provide any information as need, but we are really just not sure where to start.
1) We do not use any runtime.exec
2) No native libraries
3) We have no file I/O but plenty of network I/OI doubt if I can really help but if you close the program before running out of swap space is the memory returned?Yes if I close the program, all memory (both resident and in swap) is returned to the OS.So as I initially surmised, you seem to have a native method memory leak. How you find it I don't know.
What version of Java are you using?
Are you using one the the non-Sun Java abominations such as gcj or Openjdk? If so then don't .

2) 1.6
3) Sun's JVM
