edit /etc/profile, add this to it:
Code:
ulimit -S -m 1000000
ulimit -S -v 500000

If there are other ulimit statements in there delete them. You have to be root to edit the file.

log out, then log back in.
Code:
ulimit -a

should show much larger values, like 1GB memory; 500MB of additional virtual memory.

i downloaded that file to edit but am unsure where to add that line as there is some codeing in there already i need to make a program run at 1024 mb and maybe 3gb if i need it to i can run the program at 512 but when i tell it to use more memory it wont start up

thanks for your answer jim

If you download that file and re-upload it, you can totally hose your system if you do not ensure it is a UNIX file and not a Windows file when it returns.

Edit the file on the server in place. NEVER do what you have just done.

Perhaps PAM is also limiting your resouces. See the pam_limits(8) man page.
