>Description:
I am running 11 servers (Pentium-II 350mhz) accross the country for a virtual modem pool with USR Total Control Modem Hubs. Every server is configured for 256 pseudo-ttys. After a couple of weeks under load /bin/ps output starts showing '??' for all ttys except for the first 32 (ttyp[0-v]). My vitual modem_pool app does not key on this to run, but it causes big problems for troubleshooting. A reboot seems to fix. It appears that the kernel process table contains the correct tty info but the /bin/ps probe no longer reports it.
This has happened on 6 of the servers now. We reboot and it is fine.

So far I have not figured out what causes it. We do run and utilize up to 200 or better pseudo-ports at a time on some of the boxes.
