java.sql.SQLException: Packet for query is too large (4739923 > 1048576)

looks like the files you are trying to upload are still more than 75M. change it for example to 200M and try again.
Another reason coud be that mySQL needs restart after this change.

This is the error I get. I have more than the 4M stated in the error. Also, mentioned in the original post that I restarted MySQL.

Connection to Data Source failed
java.sql.SQLException: Packet for query is too large (4739923 > 1048576). You can change this value on the server by setting the max_allowed_packet' variable.

Any other possibilities?

I'm not much of a DB specialist but the docs say that there are 2 variables that control this - one in the client and the other in the server:
http://dev.mysql.com/doc/refman/5.5/en/packet-too-large.html

So the PHP client may also need to define this max packet size when opening the connection. (I have no idea how you set that in PHP - but in Java I'd look at the URL used to open the database connection).

Also it says:

You can also get strange problems with large packets if you are using large BLOB values but have not given mysqld access to enough memory to handle the query. If you suspect this is the case, try adding ulimit -d 256000 to the beginning of the mysqld_safe script and restarting mysqld.

Hi fellows,

I think it's a Jetbrains PHPStorm issue. I'm going to try and update to the latest build. I contacted tech for Jetbrains and that's what they said. I'll find out soon enough. Thank you for the feedback. I'll post here and respond if the update to the latest build works or not. =)

Upgrading to the latest IDE resolved the problem. God bless<><
