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 :
