10k connections likely means 10k thread stacks from the sysbench client, and then 10k thread stacks in mysqld. That can easily be 10G + 10G of memory. But this bug report provides so little detail that we can only wave hands at what the problem might be.

Consider providing more detail on bug reports if you want useful feedback. For example:

1. Share the my.cnf
2. Explain the hardware you are using (amount of memory, etc)
