Hi,

Increase the kernel parameter npty to 400 thru SAM.

Hi Shiva,

I will increase the parameter to 400 at a suitable downtime. Any particular reason to increase it to 400. The reason i am asking is , that when i do who -u |grep wc -l i get 140 to 180 during the day, but the problem is consistently occurs in any case.

How can i find out exact number of pty's being used.?

I increased the pseudo device files to 300 using
insf -n 300 -C pseudo. Is this effective from now, i.e without kernel rebuild.

Thanks and regards
Ashish

First you have to rebuild the kernel and then create the additional ptys using

#insf -e

Yes you are running out of pty devices.

you can just use w|wc -l to find out the used pty number
