I'm using MySQL Workbench 6.3.6 (64-bit) to enter DB queries, however after a short period of inactivity - I don't know exactly how long but it can't be more than 3-4 minutes (e.g. whilst I'm typing this question), the server seems to disconnect.
This isn't an issue with the server, because when I'm using Eclipse data tools, or a SSH terminal, this doesn't occur - however, the solutoin given on the question: MySQL Workbench drops connection when idle hasn't solved the issue - no matter how "low" I set the DBMS "keep-alive" interval it still loses its connection.
This may be a duplicate (but I couldn't find one that seems to really fit these circumstances)
Thanks,
David
EDIT: Have tried recommended answer below - but unfortunately despite setting it for 600s, it timed out by 4 minutes
MySQL Workbench: How to keep the connection alive
To clarify, I've included a screenshot of my SQL editor settings where I have dropped the time between keep-alive packets, and increased the time-out times - just in case I have done this incorrectly.
