Re: 1135 Can't create a new thread (errno 11)...

Is mysqlslap runnng on the same machine as the server? If so, it is competing for resources.

In my opinion, this is unreasonably high:
> --max_connections=6000

This sounds dangerously low:
> stack size (kbytes, -s) 90000

If you have over 1000 threads connected to one server, you have something else wrong.

> --concurrency=1200 --number-of-queries=1
I suspect Max_used_connections was nowhere near 1200. The queries probably came an went so fast that they were not all there at the same time. I suspect that STATUS value gives you a more accurate estimate of the concurrency mysqlslap actually achieved.

Check GLOBAL STATUS LIKE '%timeout%';
