We have a multithreaded application [u]HP-UX Version 11.11 [/u]built using aCC version [u]HP ANSI C++ B3910B A.03.37 and Rogue wave STL 2.1.1.[/u] This is a file conversion application. This application gives coredump when all the threads (say 4 threds) are simultaneously processing large files (size > 200 MB). The failure occurs at defferent points evry time. The system has 2 processors and 2 GB RAM. The application does not buffer any data for itself. It just reads the input file, transforms the input record and writes output. This application is running perfectly when the size of the fiels are less than approx 100 MB. The application uses STL components like Maps, Vectors and Queues and string also very extensively...
