Are you using omniORB 2.8 for a particular reason? It is far better
to use omniORB 3.0, since that is much more up-to-date. Apart from
anything else, the POA's support for object deactivation etc. is much
If at all possible, I strongly recommend that you use omniORB 3.0.

It sounds like what Stefan suggested -- the OS is not immediately
reclaiming unused memory from the process, so you don't see the usage
go down in top. That would also explain the odd size patterns as you
delete and create objects.
The other possibility is that your server process has got its
reference counting of object references wrong. In omniORB 2, object
references in the server process prevent servant objects being
deleted. That is no longer the case in omniORB 3.
