| I honestly can't figure out this app or suite of apps really....
I have ten apps running that only differ in look. This particular app is the busiest of the bunch. I have three instances running. The most recent issue is it just throws an exception with zero information in the log or on the screen. A restart fixes it.
Here is the error on the screen (nothing in the log files):
Re-enter
Application: | hb | Error: | java.lang.NullPointerException | Reason: |
| Stack trace: | File | Line# | Method | Package |

| NA : Non applicable, JIT activated |

There's almost nothing going on in the app. There are two WOWorkerThreads threads in the midst of reading input from the socket, but there's nothing hung waiting for a session, or an editing context lock (the usual offenders). By all accounts in this Thread dump your app looks fine. What exactly do you mean when you say "your app starts hanging"? Hanging at what point in the request? Have you tried restarting wotaskd just for good measure?

My guess is that your app is doing a bunch of socket communications and something isn't properly closing the sockets after use. I have seen similar things when using HTTPClient from apache commons-net where the http connections weren't being closed properly. Eventually the app starts hanging.
I will be interested to hear other opinions
