where one equipment format was set to "fixed" instead of "midas". lots of confusion, mdump crash,
analyzer crash, etc. (mdump fixes for this are already committed).

I am getting a scary compiler warning from MSCB code. I generally avoid touching MSCB code because I have no MSCB hardware to test it, so I am
asking the persons unnamed who wrote this code to fix it. Stock g++ on Ubuntu LTS 24.04. Thanks in advance!

the main purpose of the event buffer write cache is to prevent high contention for the
event buffer shared memory semaphore in the pathological case of very high rate of very
small events.
