I've left the other params defaulted, and just upped MSGSEG to

Are there any known problems with Xenix's message queue code ?
Any positive info on how best to avoid them (like good magic values
to tune to) ?

too (386, that is) -- some of our sites at 2.2.1 (with default tuning) seem
to have their message queues get stuck in a similar way on an irregular but
frequent basis. I'd previously blamed our code, written long before I
arrived, I hasten to add, but with this problem arising, I've begun to
wonder ... ]
