The (Pthreads) Solution: Since Pthreads, the errno variable is thread-local. Pthread_create Return pthread_create hangs. It should be safe to increase that limit a lot if you hit it. Is your OS 32 bit?

  1. If you (or a system function) set the errno variable in one thread, it won't affect the errno value in any other thread.
  2. In the above test program, even if I added sleep(1) after pthread_create(), such that every created thread was guaranteed to be over by the time out, I still couldn't increase the
  3. Subsequent calls to pthread_mutex_lock() will behave normally.
  4. Are you on a cluster? –RedX Aug 12 '11 at 10:10 1 You should change default thread stack size to start high number of threads. –osgx Aug 12 '11 at

Pthread Error Handling

In addition to that limit, there's also another limit: /proc/sys/vm/max_map_count which limits the maximum mmapped segments and at least recent kernels will mmap memory per thread. anchor The Emscripten implementation does also not support multiprocessing via fork() and join().

And, the most important: the Pthreads APIs do not set the global variable errno. check over here the appropriate error code otherwise. Late on, I came to realize that there is a default stack space for a thread, which is about 8 MB, so 384x8M=3GB, a fair limit in a 32-bit system.
