James,

A bit more info might be necessary to resolve this...

Your app hangs? As in it deadlocks? Or as in takes a seemingly unnecessary amount of time to compute something? How did you obtain the stack below, was an exception thrown, or did you manually suspend the worker thread and copy it? What are other threads in your app doing? How reproducible is this? What kind of an object is being formatted?

If it is a deadlock, and your worker thread stops for seemingly no reason at NSTimestampFormater.format(...), it could be that either the method or a block in it is synchronized and waiting for something to release the lock.

i'm pulling my hair out sometime trying to find my errors. my app hangs and this stack doesn't do me much good. i see PageViewer is the last component my app talked to and then i can't find nuttin'...

can someone please push or shove me in the right direction to use eclipse to debug my apps? most of the time eclipse will tell me the .java file and line # of the error.

thanks,
