Randomly Cant connect to local MySQL?

This might be related to another problem i am having. But in this case my app was idling and i had a crash in my GetConnection() on conn.open().

Since i was idling i figure it had comething to do with my queue in the background and possibly garbage collection? I took a look at netstat and found 16 connections.

Does mysql only accept 16 connections by default? is it because i am opening too many connections? this IS because of not closing/disposing connections? might commands have something to do with it or is that completely not the problem and is a MySqlConnection issue?

Are you disposing your connections? MySQL itself has connection pooling and the way to return connections to the pool is by disposing them.

Garbage collection should not pose a problem if you are correctly disposing your connections after you've used them.

I've encountered this when using the MySQL connector. The work around I use is to manually turn off connection pooling in the connection string by adding "pooling=false;" to the end of the connection string. It will hurt your scalability but allow your application to run.
