FWIW, I can disable entire parts of the application and have already narrowed down reproduction of this issue to the 200 threads that make the webservice calls, so it doesn't have anything to do with any of the GUI or other background services that my application executes.

I'm curious to know how this problem would be easier to narrow down if it were written in C. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
