You may have hit a limit in MySQL. I'm running 15 cameras and when several users connect to the montage view we get a max connections error. To fix this I've increased the MySQL connections to 1000:

sudo nano /etc/mysql/my.cnf

look for max_connections = and change the value to 1000 (or greater)

ctrl + o to save the changes
ctrl + x to close nano

restart MySQL or restart the PC.
