Hej boost-users.

I'm compiling a test thread program where I create 255 thread but I get an "Program received signal SIGABRT, Aborted." after thread 254 I running redhat 7.3 and using boost 1.28.00. Is it an OS problem or a boost problem?

You've hit an OS limit. See http://pauillac.inria.fr/~xleroy/linuxthreads/faq.html, FAQ D.9. I'm assuming the library detected this and through a boost::thread_resource_error which you failed to catch resulting in the SIGABRT? William E. Kempf
