You may have to increase the npty value and rebuild the kernel.


kmtune |grep npty .


Thanks,

You have run out of pseudo tty's

Need to rebuild kernel with an increase in npty value

Hi Oscar,

You are running out of pty ,

And need to increase the kernel parameter for this value,

Hope you are having npty defined 60. And need to increase ,
Do the following:

# kmtune -s npty=200
# kmtune -s nsrpty=200
# kmtune -s nstrtel=200

# ./mk_kernel
# ./kmupdate
# shutdown -r -y 0


After reboot , check the pty values,
# kmtune | grep -e "npty" -e "nsrpty" -e "nstrtel"


Enjoy..
Cheers,
Raj

Hi

Like others who mentioned here ,you ran out of pty's, you need to reboot and bring the server backup (run a os backup) change the kernel parameter npty.
