I think I found the culprit.

sheliak# apcaccess status
<snip>
DSHUTD   : 020 Seconds
<snip>

20 seconds is probably not enough for my old Sparc.

Looking at the eeprom I have
sheliak# apcaccess eeprom

Valid EPROM values for the SMART-UPS 700 RM

I tried to change the sleep value with
sheliak# apcupsd --configure SLEEP 180
Attempting to configure UPS ...

Reading updated UPS configuration ...

Does it come from apcupsd or is it my UPS which doesn't allow eeprom changes?

Does someone have a workaround?
