Limit the number of max threads used by a process in linux kernel

  • 772

I think I have found something that I need from the Linux kernel that is not currently implemented.

I need a way to set a max thread limit per process.

Is this possible?

    From StackOverflow:

    Linux doesn't have a separate threads per process limit, just a limit on the total number of processes on the system (threads are essentially just processes with a shared address space on Linux) which you can view like this:

    cat /proc/sys/kernel/threads-max

    The default is the number of memory pages/4. You can increase this like:

    echo 100000 > /proc/sys/kernel/threads-max

    There is also a limit on the number of processes (an hence threads) that a single user may create, see ulimit/getrlimit for details regarding these limits.
