There are no issues with these tables. While they are growing, they are way under their limits.
What's your real problem?

>My memory consumption is very high:
This is a good thing. Are you having problems starting new processes?
You have no page outs.
>does the following output of ipcs command, indicates any problems with memory:
It just says that Oracle has some shared memory: 8.5 and 6.5 GB.

what happened was that an coleague was trying to acess the DB of this server, from another hp-ux server, and she was having shared memory errors, and trhown out of the application.
So we rebooted the DB server, (306 days uptime), and memory consumption was brought down to 70% seen in glance, and she can now acess the DB
