Re: [cgiwrap-users] Proper Use of --with-rlimit-* Configuration Options

[Neulinger, N. <nn...@ms...>]

It's going to totally depend on what the users are doing and your
particular system. I've seen perfectly reasonable CGI scripts spike to a
hundred meg plus for split seconds.

For documentation of the limits, 'man setrlimit' should give you useful
information.
