My server runs some maps that are over 40Mb with no problems.
However, after a few days, the server becomes a little slower than usual so I simply reboot it and all is running fast & fine.
The
size of a map doesn't have much to do with a server crashing.
In most cases, the cause of a server crash is due to a bad file, not enough available resources or too many tasks running on the server machine.
Are you running a
dedicated server ?
Are you using 'Black Bag Opps' server manager ?
I have been running game servers for many years and have learned a few techniques to keep them running at high performance.
