However I have observed in some heavily loaded servers that between the time you execute a SHOW STATUS and SHOW FULL PROCESSLIST some of the running processes may finish. I tried the following command: [code] SHOW GLOBAL STATUS LIKE 'threads_running'; SHOW PROCESSLIST; [/code] The same can be done with 'threads_connected'. Under normal conditions the values of the variables and the line count on the processlist should be the same, but under heavy load, I've seen differences between the 2. Have you had the same experience? My $.02 G This is an interesting technique.
