IPCS and semaphore limits on 3030

[x7428 fred/arpanet user]

We have two IRIS 3030's and have run into several system limits:
	o  Only 40 IPCS meessages can be present in the system at any
	   time.  If more than 40 are sent, all IPCS message send and
	   receive operations will hang.

	o  Only 8K of messages can be present on any combination of
	   IPCS queues at any time or the same symptoms as above appear.

	o  Only 10 semaphores keys can be created

	o  Only 50 actual semaphores can be created

So as you can see, these limits can really hamper a multi-task application.
We realize that the kernel would have to be modified to change these, but
since we don't have the code, this is not an alternative.  We were wondering
if anybody has devised software to emulate some of these functions using
another resource (i.e.  using shared memory to simulate message queues)
Also, if anybody has the kernel changes reqd., this might be useful to us
as we might be able to get the kernel source code.  ANY information you can
provide would be very appreciated.
