Jeffrey B commented on AMQCPP-449:
----------------------------------
Thanks Tim, but I tried adding that in my file and using your file directly and
neither worked. I still have the issue. I gather more information from
PlatformThread.cpp. I placed counters on each of the mutex functions and
printed them out in the exception.
createdMutex: 82 lockedMutex: 1765 tryLockedMutex: 197 unlockedMutex: 1961
destroyedMutex: 21 createdRWMutex: 0 readerLockedMutex: 0 writerLockedMutex: 0
tryReaderLockedMutex: 0 tryWriterLockedMutex: 0 unlockedRWMutex: 0
destroyedRWMutex: 0
These numbers are very consistent. lockedMutex and tryLockedMutex are usually
+-2, everything else is always the same. Also if I place a breakpoint just
before the exception is thrown and I inspect the value of mutex, it is
consistently the same value 0x2000000040089480. Hope this helps somehow. Let
me know if there is any better information I can gather.
Thanks

> Key: AMQCPP-449
> URL: https://issues.apache.org/jira/browse/AMQCPP-449
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Decaf
> Affects Versions: 3.5.0
> Environment: HPUX 11.31
> Reporter: Jeffrey B
> Assignee: Timothy Bish
> Priority: Critical
> Labels: HPUX, crash, destructor, exception, runtime, thread
> Attachments: amqdriver.cpp, amqdriver.cpp
>
>
> Whenever my simple driver application or my receiver application call the
> shutdownLibrary() method at the end, as the program is going through
> desctuctors for threads it prints and causes a core dump
> aCC runtime: Unexpected exception of type
> "decaf::lang::exceptions::RuntimeException".
> aCC runtime: what(): Failed to Lock OS Mutex
> Abort(coredump)
> I added another catch and print in decaf/lang/Thread.cpp about line 133 and
> on decaf/internal/util/concurrent/unix/PlatformThread.cpp about line 76 i
> printed out ther error number return from pthread_mutex_lock()
> Now i get:
> Failed to Lock OS Mutex, Error num: 22
> FILE: decaf/internal/util/concurrent/unix/PlatformThread.cpp, LINE: 78
> aCC runtime: Unexpected exception of type
> "decaf::lang::exceptions::RuntimeException".
> aCC runtime: what(): Failed to Lock OS Mutex, Error num: 22
> Abort(coredump)
> Error 22 is EINVAL and can have two meanings on my system:
> mutex is a PTHREAD_PRIO_PROTECT mutex and the caller's priority is
> higher than mutex's priority ceiling.
> mutex is not an initialized mutex.
> I'll try and upload my code to see if this happens on other systems as well.
