maximum number of threads allowed to run

Question

Maximum number of threads in my linux system is 93946. I got this value from cat /proc/sys/kernel/threads-max. But when I create around 32768 threads I got error

cannot create new native threads

• How can I create maximum number of threads(around 93946)?

• If it is not possible to create maximum number of threads (93946), how can I find maximum number of threads allowed to run?

Answer 1

please check out /proc/sys/kernel/pid_max. Since threads have their own pid, this value limits the maximum number of threads too.

Answer 2

You can find max thread with command:

sysctl -a| grep kernel.threads-max

Edit the /etc/sysctl.conf file and add new value

kernel.threads-max = 93946

Make change effective with sysctl -p
