How to Kill All MySQL Sleeping Processes
for i in `mysql -e "show processlist" | awk '/Sleep/ {print $1}'` ; do mysql -e "KILL $i;"; doneHaving a lot of MySQL sleeping processes can cause a huge spike in your CPU load.
Here is a simple one-line command which would kill all of the current sleeping MySQL processes:
for i in `mysql -e "show processlist" | awk '/Sleep/ {print $1}'` ; do mysql -e "KILL $i;"; done
Note that this is a temporary solution, I would highly recommend investigating and fixing the root cause of the problem. For example, you could configure the wait_timeout variable to a specific time that MySQL should wait before closing idle connections.
Hope that it helps.
