Hello,

On a DB2 9.5FP3a on AIX 6.1:
After running "db2stop", there were 69 processes owned by db2inst1 called
"aioserver". Isn't that strange? If it's expected: Can someone explain
why?

You seem to have the same issue as described in this thread:
http://unix.ittoolbox.com/groups/technical-functional/ibm-aix-l/aioserver-processes-not-cleaning-up-2623793?cv=expanded

Also have a look at this documentation on the AIO-subsystem and how to
tune it:
