Description
Mysql connections to external logstore are not reused/cached, so the amount of mysql connections is increasing.
This can best be seen during automated course backup. Every database reading creates a new database connection. This connections are terminated when backup process is finished.
Probably solution: Use a global variable $DBEXT like $DB, where the external mysql connection is cached.
