increase default max map and file counts

Browse source 
Explained in a comment:

 behavior for those who had previously set their system limits high,
 and weren't experiencing any bad behavior. Ideally you want these set
 a bit below your system limits.

a bit slower, and cause slower restarts, but is generally fine.
