Tru64 4.0G - problems with alocate tty's

We have a problem with a TRU64 4.0D running navision, all users connect via ssh2
and are running navision in a ssh2 session.

The server has problems when it reaches 254 users, then the user gets
"fail to allocate ttyâ s"

We have changeds maxusers to 512 in the kernel configuration and created 512 tty devices.
But still same result. Any hint

Brian,

Check /sbin/sysconfig -q pts, it probably says "nptys=255".
So add an entry in /etc/sysconfigtab

pts:
nptys = 640

Unfortunately you have to reboot to make it
effective.

Additional remark:

You mention 2 versions in your entry.
I do not have a V4.0D handy, but it's possible that in /sys/conf/HOSTNAME you have

pseudo-device pty 255

If you have pts in sysconfig, you can safely remove that line from the config-file.
