I'm running Xenix 2.2.2 on a PS/2 60 with 2 meg of memory.

I'm developing a commercial application which uses SysV
message queues to pas info. between two servers and a
variable number of other processes.

I have attempted several times to increase the kernel allocation
for message queues, but never manage to get more than 8192 bytes.
The parameters I'm changing are:

	MSGMNI	10
	MSGSSZ	8
	MSGTQL	60
	MSGMAX	(MSGSEG*MSGSSZ)
	MSGMNB	(MSGSEG*MSGSSZ)
	MSGSEG	0

the numbers to the left are default values. MSGSEG is altered at boot-up
time depending on the amount of memory.

I would like to get around 200 messages (MSGTQL) and 100K bytes of
total size (MSGMNB?). Every alteration I make to the parameters
either gives me 8k or 0 bytes. Does anyone know how to do this??

I need to solve this soon so email is fine ( ..!uunet!sean!news ).

Thanks in advance,
Mike Anderson,
