The EntityManager is closed.  

After I get a DBAL exception when inserting data, EntityManager closes and I\'m not

Answer 1

I had this issue. This how I fixed it.

The connection seems to close while trying to flush or persist. Trying to reopen it is a bad choice because creates new issues. I tryed to understand why the connection was closed and found that I was doing too many modifications before the persist.

persist() earlier solved the issue.
