How to repeat:
Run a query against any table a couple times and the app crashes.

I have been experiencing this problem too.  If you run more than 5 queries you’re almost guaranteed to crash Workbench.  I’m running MySQL Workbench 6.3.7 on macOS Sierra 10.12.1.

Hello Clint Kahler,

Thank you for the bug report.
This is most likely duplicate of Bug #82951, Please check the workaround(set SSH keepalive(default is disabled)  to 30 sec or 60 sec) mentioned in Bug #82951 will helps you.

Thanks,
Chiranjeevi.
