The man page for the mq_open(2) function fails to state that another possible
cause of the return value being set to -1, with error set to EINVAL, is that
the call, if permitted, would cause one or another of the following kernel
tunable limit parameters to be exceeded:


kern.mqueue.maxmq
kern.mqueue.maxmsgsize
kern.mqueue.maxmsg
