Hello Jaeyeon,

I assume the quota of your cpu-session gets exceeded. If you got something like: "Quota exceeded!" just before your thread's creation failed, that's the actual reason for it. You can increase that value by creating your own cpu-session, and giving enough memory to it, like for instance:

Session_capability cap = env()->parent()->session(Cpu_session::service_name(), "ram_quota=32K")); Cpu_session_client cpu_cli(cap); cpu_cli.create_thread("mythread"); ...

Regards Stefan

Hi,

While I am trying to create many threads by using Genode::Thread, I’ve found that only up to 31 threads could be created. I’ve got the following message when more than 32 threads is created:

C++ runtime: Genode::Cpu_session::Thread_creation_failed.

Do you have any idea on this problem?

Thanks,

Jaeyeon Kang
