Good time of day!
The problem is the following:
System: Intel, Linux RedHat 7.2, Kernel 2.4.19, gcc-3.3.
The program works as a server.
When new request comes, it creates a pthread.
There can not be created 2 threads at the same time,
in this case we just do not create new thread.
Every called thread completes and exits, allowing next thread to be called.
After a number of such calls (200,000 on my system) operational system does not
allows to create a new thread et all, in any case returning EAGAIN error,
so the system stops to work.
In case i just create one infinite thread, wich makes corresponding tasks,
and starting it using flags, this problem is never arrise.
Could you please, explain me a possible source of this error,
Thank you, looks like it works fine, but if you put this code before pthread_create,
in other case it will stop the main program when pthread works
But why this error arrise, is 0.1 second is not enough for finishing pthread?
Thanks a lot,
Actually, by adding pthread_join(processor, NULL); you make sure that the main program waits for the child thread to terminate. So, it's like
1.main threads creates child thread
2.main thread waits for the child thread to terminate.(due to pthread_join)
3.when the child thread terminates, all the resources used my the child thread is freed.
4. go back to step 1.
