The fd number can differ depending on what type of login you made. If you do console, su or ssh login the number of FD can be different if you don’t have pam_limits enabled on /etc/pam.d/(ssh|su|login). Second, doing grep, probably you catch another processes which in a way or other is using your username. The correct way is to use lsof -u username and not grep.

I’m using this command:
[root@testserver ~]#lsof | grep username | wc -l 4719
But I can’t understand it, because the limit is lower than result:
[root@testserver ~]# ulimit -a | grep open open files (-n) 4096
What am I doing / reading wrong?
