Multithreaded System On 4 Cpu Linux Machine, process stuck on certain thread
hello All,
i've developed a process that uses 5-20 threads.
after several seconds from start of the program the process hangs
doing only one of the threads work - either main thread or others - but only one.
done the -D_REENTRANT using gcc c++ 3.2 linux redhat 9 .
what am i doing wrong? - on a single cpu machine it works fine
most of the times - there is no core and the process works but for only
one thread.
other info :
