If the users are connecting via telnet, and they are getting kicked off of the telnet sessions, most likely, the problem isn't in Informix. The error showing up in the online log is most likely just a message telling you that the user went away unexpectedly. I would check the date and time that telnetd was last started. I'd bet it was at about the same time as you encountered the problem. telnetd died, killing the terminals, and then init started it back up, which is why it let you log in. If this is the case, you might have better luck posting a message to that effect on the SCO newsgroup. -- # unrm / ksh: unrm: not found # man cpio Sent via Deja.com http://www.deja.com/ Before you buy.
