It's rather brave to use Cygwin for a production RT instance.

Your server is running out of memory, likely because the maximum memory
usages of MySQL and Apache aren't properly configured to coexist
peacefully within the limits of your server.  Most people install Apache
and MySQL without tuning them, and then eventually run into problems
like this.

You should read about how to tune Apache and MySQL.  Starting with
mysqltuner.pl is a good start, but nothing will do this automatically
for you.  You'll need to manually make changes.

The new queues have nothing in particular to do with it.

Whatever research you did was mistaken or misleading.  "Rebasing" has
nothing to do with MySQL.  It is a concept in git, a source code
management tool, used during development.  You don't need to worry about
