Help With this ERROR:QThread::start: Thread creation error

analyst009

Hi,

I am creating many threads (800) on Linux and getting error "QThread::start: Thread creation error". On my system, OS limit for max thraed is pretty high but still I am getting the error. What can I do resolve it? Is there any way to increase the max thread count for QT?

Any pointer will be very helpful.

Thanks & Regards,
Chandan

Hi analyst009,

why do you want to create 800 threads? That does not make any sense. It costs resources, time (for thread switching etc.) and brings no advantage.

Could you explain a bit more, what you want to achieve? For me (without knowing the background of your app) it sounds like a design problem of your app...

Hello

I sometime used that much thread just to burst API calls on supposed thread-safe API (robustness testing). The more thread, the more risk to bump into a race condition...
Not common use, but it can happen (note, I never tried with QThread however)

Hi Gerolf,

Thanks for the reply.
This is an application used for testing some thing which needs to create 800 threads.

Thanks & Reagrds,
