The kernel has a maximum command-line length, but it that only gets checked when an external executable is run.

The better way to stop malicious people from using up all your memory is to specify a datasize limit in /etc/login.conf . -- Dan Nelson dnelson@emsphone.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
