[Anonymous]

Hi,
I upgrad my Talend Platform dor MDM with Big DATA to the current version (5.4.2).
I have some anormal errors and bugs (See the server log bellow) that I hadn't with the last version. These errors occurs when I try to access the records from the web UI.
PS: I am using MySQM database.
Thanks in advance.

Hi,
The line:

com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: No operations allowed after connection closed.

... looks rather suspicious. Please check the following:
* Are you sure nothing changed on the MySQL side?
* The database connection configuration did not change?
* Do you have any other exception before this one that may indicate the reason of the connection close?
In any case, MySQL usage indicates you're using Enterprise version, so you can reach Talend Support ( https://support.talend.com) for assistance and diagnostic.

I haven't change anything on the MySQL side.

Great, please also check for any exception occurring before this one that could explain the connection close.
