hi,

where can i find info abt the maximum no. of procesess supported by the kernel..i have a 2.2.16-22(redhat 7.0 )kernel.
and i haven't compiled this kernel after installation...

in general what is the maximum processes that a kernel can support..or is there no limit to this parameter???

thanx ,
Anoop.

Hi anoop ,

The maximum number of process the linux kernel supports is a totally different issue and it's related to the way the kernel does its process management

On Redhat 6.0, and in kernels downloaded from kernel.org, the limit on the total number of processes is 512, and the limit on the number of tasks per user is half of that.

Since Redhat 6.1, using the standard redhat supplied kernel, the total number of process is 2560, and the max per user is 2048.

If you need to increase the limits, you will need to modify the /usr/src/linux/include/tasks.h file. The parameters to change are NR_TASKS and MAX_TASKS_PER_USER.

In all cases, the maximum value for these parameters is 4092

but i hear that in kernel 4.x it has been change to +100,000 but then iam not aboslutely sure .

sorry if this hasnt helped.

regards,
Xanthium.

ok thanx for the reply,
i'll look into it..

then what is this process id ???how is it related to the kernel process management?

bye
