I have a post-upgrade problem:
Computer: Compaq Proliant 1500, duel processor Pentium 166,
RAID 5 on Compaq IDA, Netflex-3 NIC (100MB), 16GB Compaq
SCSI DAT tape
OS: was SCO Openserver 5.0.2 Enterprise Edition, 130-user
Compaq EFS 5.13
now SCO Openserver 5.0.5 Enterprise Edition, 130-user
Compaq EFS 5.21
Main App: Custom BBX Inventory Control / Order Entry System
Network: Ethernet, TCP/IP, ISDN router to internet ISP
Other upgrade issues having been resolved or worked around I am left with:
When the morning shift (about 25 users) logs in all goes well. About noon,
as the second shift overlaps the first, the system balks at allowing more
than about 70 users on the system. By about 3 o'clock, things settle down
and we can get up to our working number of 84 logins.
There is nothing added to */crontabs/root, except a backup script that runs
at midnight. All stune parameters are adequate for a 130-user system. All
licenses are registered. There are no errors or usual messages on the
console or in /usr/adm/messages, syslog or syslogt. No failures in any
streams. TCP/IP stack is configures for 256 connections and there are 198
/dev/ttyp* entries. There are no internet, NIS, or PC-Interface services
running. The system worked wonderfully prior to adding the second
processor and SMP, and performing the 5.0.5 upgrade. Connections are made
using James River Group ICE.TCP telnet (SCO ANSI emulation).
What else do I need to look at that might have been changed during the
upgrade? What change(s) in the versions would cause this situation? I
have been installing and administering SCO systems for over eight years,
and this one has me stumped!
I still need to add an ADIC 40GB tape drive and a DPT Smart-IV RAID
controller and an external drive tower and file systems to the server. I
am holding off until I can resolve this user login issue. I am already
facing a user revolt and disgruntled management.
I will discuss my other issues with the 5.0.5 upgrade and it's
documentation with SCO at next months QBB in Dallas.

As usual, management says that my problems are my own and they will disavow
any knowledge of my activities.
