> Issue Type: Bug
> Components: SAX/SAX2
> Affects Versions: 2.5.0
> Environment: Xerces-C++ version number :- xerces-c_2_5_0-hpux_11-acc_a03
> Platform :- HP-UX 11
> Operating system and version number :- HP-UX Unix Version 11.0

> Operating system and version number HP-UX Unix Version 11.0
> Compiler and version number aCC compiler - HP aC++ Version A.03.37
> The schema document has no issues and the the XML string also has no issues, because both work well when i used ALTOVA tool for parsing.

> What happened
> I am using the SAX2 parser to parse my XML files.
> I dont use any threads here, its a single flow of events from parser creation till the parsing of the xml file.
> I observe that in my logs, once the XML string is created and sent to the piece of code mentioned above. The parser hangs in the parse method.
> As per its behaviour, it is supposed to call the "start document" "statrt element" functions whihc are overloaded in my classes.
> The last log statement that i see is the " start document " after that i dont get anything. My application proceeds with other threads where i do socket operations totally un-related to the XML logic or piece of code.
> Here are the logs
