[Proc] wierd behavior of /proc
Hi everyone,
Quick question for all of you:
Here is the weird behavior:
--
[root@XXXX]:~ # ls -al /proc/2574*
ls: cannot access /proc/2574*: No such file or directory
[root@XXXX]:~ # ls -ald /proc/25740
dr-xr-xr-x 7 mysql mysql 0 Oct 12 10:40 /proc/25740
[root@XXXX]:~ # cd /proc/25740
[root@XXXX]:/proc/25740 # ps -edf | grep 25740
root 7937 7485 0 14:14 pts/12 00:00:00 grep 25740
[root@XXXX]:/proc/25740 # cat status
