-how long do you monitor after r/w finish? More than 900 seconds. I executed the following command last Saturday and today, the output was same. sudo lsof -p 5509 | wc -l
And the result from /proc: ls -ltr /proc/5509/fd | grep socket | grep "Aug 13" | wc -l 134 sudo ls -ltr /proc/5509/fd | grep socket | grep "Aug 19" | wc -l 0 In which configuration file can I find ms_connection_idle_timeout?
