    All Application threads stopped for 3~5 minutes

      Hi.
      Our Java application experiences sudden 3~5 minutes application threads stops.
      Our Application is run by 1 process and 300~400 threads.
      All threads are stopped suddenly and are run after 3~5 minutes or more.
      I can't analyze any patten but I experience this problem once or twice a day.
      I guess it is caused by application bug, java bug or Solaris bug and so on.
      I have difficulty to solve this problem and I can't find what causes it.
      Please give advice on this problem.

      (*) Our system :
      SunOS Solaris 5.10 Generic_138888-03 sun4u sparc SUNW,Sun-Fire-V890 (32G Mem)
