So persumably all three ip's below are on the same physical box.

Just to confirm, Apache is running twice, it's not listening on two
different ip addresses.
So each then starts up it's own seperate JVM,

I guess then you should be able to duplicate this problem by running the
connect from two seperate java programs running at the same time (it
might be worth trying just to get apache out of the picture for figuring
out the problem).

If they are all on the same physical machine, then it doesn't matter
that apache

netstat may help at least in terms of working out the socket connections
between the client programs/ interserver/ and interbase. And that also
may help you with the problem.

Sorry I don't have a direct answer.
