Linux中每个进程的最大线程数? [英] Maximum number of threads per process in Linux?

问题描述

Linux下一个进程最多可以创建多少个线程?

What is the maximum number of threads that can be created by a process under Linux?

如何(如果可能)修改此值?

How (if possible) can this value be modified?

推荐答案

Linux的每个进程限制没有单独的线程，只是系统上进程总数的限制(线程本质上是具有共享进程的进程在Linux上的地址空间)，您可以这样查看:

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

默认值为内存页数/4.您可以像这样增加它:

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

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

单个用户可以创建的进程(以及线程)数量也受到限制，有关这些限制的详细信息，请参见ulimit/getrlimit.

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