Hi,
I applied a high load to mysql, both 'show status' and ps always showed 1 thread running. I am wondering if the issue has been discussed somewhere and a corresponding bug has been filed, and/or also if I have misconfigured mysql in any ways.
'show innodb status' showed transactions "not started" with different thread ids.
Suggestions/pointers are appreciated.
Here are my testing environment, and the results of the aforementioned commands:
