If it the out of memory occurs directly after the application or DB2 is started, you might want to check, to which value the parameter database_memory is set, or maybe one of the other memory parameter for DB2.
Trivia:
IBM DB2 9.5 Information Center for Linux, UNIX, and Windows
How to do check:
IBM DB2 9.5 Information Center for Linux, UNIX, and Windows
When it occurs, just to make sure, use
svmon -P | grep -p Pid to determin which is using Paging Space. You will simply see it, when there is not a null in the column "Pgsp" to find the culprit.
So it could be, that you overcommit memory to the database, that you don't even have (in the old setup) as physical RAM available.
Another thing comes to my mind - has your OS been "tuned"? Maybe post the output of
vmo -F -L lru_file_repage -L minperm% -L maxperm% -L maxclient% -L maxpin%.

Hey guys,
since AIX 5.3 reaches EOS on april 2012, I really need to update my systems asap.
Any experience on upgrading directly to 7.1, with sap/db2/oracle?
could do fresh installs and import my sap/db vgs, but this would be a lot of work
