ENOMEM?

Dear Lazy Web,

Why does calling pthread_mutex_lock and pthread_mutex_unlock in a tight loop cause pthread_create to error out with ENOMEM?

I could accept something is wrong with my code changes, but by removing the lock/unlock around the shared variables it works correctly.(*) The lock/unlock are in tight loops, but putting them in doesn’t change the flow of the program at all. Any ideas on how this could be causing a pthread_create to fail with ENOMEM?

* Correctly. It crashes randomly when starting because the variables aren’t locked correctly, but sometimes it finishes.

I would like to blame linux somehow. I wish this code ran on freebsd so I could… But testing is for wimps anyways.

Thanks,

Paul
