OK, so memory is you problem. pgscan/s column indicates that system was very actively looking for memory pages to free up. Can you also post output of:
Code:
sar -f /var/adm/sa/sa27 -s 09:00 -e 15:00 -r

to check the amount of free memory over time.

The average scanrate since last reboot is 1239. This value stays equal to zero when enough RAM is installed.
