> Key: XERCESC-1779
> URL: https://issues.apache.org/jira/browse/XERCESC-1779
> Project: Xerces-C++
> Issue Type: Bug
> Components: DOM
> Affects Versions: 2.7.0
> Environment: Windows XP, VC6
> Reporter: Sanish Kanjany
> Fix For: 3.0.1
>
>
> My program has more than one threads which are having atleast one instance of
> DOMParser. Some times main thread (not sure about other threads) hangs on
> XMLPlatformUtils::lockMutex or XMLPlatformUtils::unlockMutex. It is not
> predictable from which function call it goes to lock. From the function call
> stack of the waiting thread, its coming from
> DOMParser::resetCachedGrammarPool. Here is a sample call stack.
