PROBLEM: (MGO103520 STLQ85019 STLQ83203) (Patch ID: OSF425-428) ******** This patch fixes a problem whereby applications linked with both libraries libaio_raw and libpthread would fail at startup with the error message: Internal AIO consistency error: Cannot use libaio_raw with threads.... Either relink without -pthread or link -laio, not -laio_raw. Aborting... Please note that with this patch installed, the following performance impact can be experienced: If the application is linked with libaio_raw AND libpthread, there is a minor performance penalty due to the necessary locking required to make libaio_raw thread safe. If the application is linked with libaio_raw and NOT libpthread, no performance penalty results because the locking subsystem recognizes that threads are not in use and, effectively, turns all lock requests into NOPs.
