> I need to to change the ulimit to 16384(ulimit -n 16384) on boot on > Centos 5.4 64 bit. How do I do that? After replying to you, I tested the "solution" I gave you and it didn't work. I found a working solution. I added the following line to /etc/profile: ulimit -n 16384 This works as the general default setting. If you want to apply the setting to a particular user, you should add it to the .bash_profile file in the user's home directory. I know it works because I just tested it and it survived the server's reboot. I ran "ulimit -a" and the new value was there. Please excuse me for the involuntary mislead. I was pretty sure that it did work "once upon a time"...
