I have this little procedure that work for me all the time
1. Check bpsched logs errors
tail -20000f log.<date>
2. Check Activity monitor changes
bpdbjobs -AUTOREFRESH -STAY_ALIVE
3. Check Drives down and AVR
for SER in `bpstulist | awk '{print $3}' | sort -u`
{
print "=========== $SER"
vmoprcmd -h $SER -d | egrep -i 'avr|down'
}
4. Check OS messages
more /var/adm/messages
SUN: dmesg
AIX: errpt -a | more
5. Check Core dumps
file /core
6. Check IPCS times
ipcs -qa
let us know if worked for you.
