Client programs work fine most the time.

[ccameron at cgydc002 bin]$ sudo ./upsc SmartUPS1400 at localhost
battery.alarm.threshold: 0
battery.charge: 100.0
battery.charge.restart: 15
... etc.

Nagios has a client program, which fails maybe 20% of the time.

I'm not sure what more useful information I can give. It's a RedHat 9 
system running NUT 2.0.4. The UPS is a SmartUPS 1400, connected via a 
serial cable. At one point this was working fine, then these came out of 
no where. This was on NUT 2.0.1 I believe. I'm using the same config 
files now as with the previous version.

ups.conf:
[SmartUPS1400]
        driver = apcsmart
        port = /dev/ttyS1


upsd.conf:
ACL all 0.0.0.0/0
ACL localhost 127.0.0.1/32
ACL accounting 192.168.121.11/32

ACCEPT localhost accounting
REJECT all



upsd.users:
[nut]
        password = password
        allowfrom = localhost accounting
        upsmon master
