The following are the Mysql 'max_user_connections' limits.
.NET Basic plan - 10 MAX
.NET Advance plan - 10 MAX
.NET Premium plan - 20 MAX
Semi plans - 40 MAX
Normally, 10 is more than enough. But if your application doesn't close
the connection after you use it, then it'll accumulate dead connections
and eventually, you'll run out with error message.
1. You can use the Database
manager -> Mysql Manager -> Flash DB function to flush all the
dead connections to fix this problem.
2. Upgrade your account to higher hosting plan package for more connections.
