After a period of inactivity workbench generates:

Error Code: 2006. MySQL server has gone away

- It should reconnect automatically if given a new query. This behaviour did not occur in version 6.3.2

The DBMS connection keep-alive parameters (the three parameters in "MYSQL Session") have no apparent effect.

Connected database is running on MySQL 5.6.14 community server, on Windows 2012 server.

The workaround is to close workbench and reload - which is not productive. 

How to repeat:
Run a query, minimise, wait 20 minutes. Then retry.

Suggested fix:
Behaviour should be the same as the 6.3.2. If the MYSQL server has gone away, it should automatically reconnect.

I'm a big fan of MySQL workbench and am impressed it's free! Great tool, thank you for your hard work on it.

I have encountered the same regression -- for me too it worked in previous versions of MySQL Workbench.

First, I can add a partial workaround: In the menus, select "Query" -> "Reconnect to server". (Unfortunately there is no keyboard shortcut). However, this workaround does not fix all problems.

For example, if you click to expand a database in the "Schemas" tab when the connection has "gone away", the tables will not be visible. Even after reconnecting, "Refresh all" has no effect. The only way to get the table list is to collapse the database and re-open it. These kinds of secondary problems expand the scope of the error.

For me this occurs within just a couple minutes of being idle. I have to switch to a different client until an auto reconnect is implemented since I feel its impacting my users productivity.

Well I see it's been a year since the last comment on this. I just started using Workbench again and am running into this issue now. I guess I'll have to content myself with phpMyadmin.
