There are many Sleep threads executing show processlist in Mysql.

The execution of show processlist in Mysql shows many Sleep threads. Due to Program Design Bugs, there are many Sleep threads in the database currently used in this project. I have found many solutions and have not found any final solutions. You can only use the following method temporarily: Write a shell file, such as killSleepProcess. sh.

[Plain] while: do n = 'mysqladmin-uroot-p *** processlist | grep-I sleep | wc-l 'date = 'date + % Y % m % d \ [% H: % M: % S] 'echo $ n if ["$ n"-gt 10] then for I in 'mysqladmin-uroot-p *** processlist | grep-I sleep | awk '{ print $2} ''do mysqladmin-uroot-p *** kill $ I done echo "sleep is too I killed it">/root/tmp/sleep. log echo "$ date: $ n" >>/ root/tmp/sleep. log fi sleep 120 # Run done once every 120 seconds

 

The result of the above shell code is: kill all the threads in the Sleep state queried by show processlist.
