-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
134
sudo ls -ltr /proc/5509/fd | grep socket | grep "Aug 19" | wc -l
0
0
In which configuration file can I find ms_connection_idle_timeout?
