mmap and changing buffers

I noticed recently if I change the buffers, and the mmap file size is changing zm doesn't work correctly anymore.

I have to remove the /dev/shm/.zm.mmap.1 file manually after it zm generates the new file with a correct size...

Generally speaking if you change buffers etc you should restart ZM to make sure everything picks up the new values. Lots of things attach to the shared memory and it cannot be resized if anything is using it.

I have restarted ZM from web interface, but the mmap file didn't change

only if I have deleted it and restarted ZM.

Yes, I noticed this earlier. I have added a mod to remove them on exit.
