Description
"Apache2::Resource" uses the "BSD::Resource" module, which uses the C
function "setrlimit" to set limits on system resources such as memory
and cpu usage.
Any "RLIMIT" operation available to limit on your system can be set by
defining that operation as an environment variable with a "PERL_"
prefix. See your system "setrlimit" manpage for available resources
which can be limited.
The following limit values are in megabytes: "DATA", "RSS", "STACK",
"FSIZE", "CORE", "MEMLOCK"; all others are treated as their natural
unit.
If the value of the variable is of the form "S:H", "S" is treated as
the soft limit, and "H" is the hard limit. If it is just a single
number, it is used for both soft and hard limits.
Defaults
To set reasonable defaults for all RLIMITs, add this to your
httpd.conf:
PerlSetEnv PERL_RLIMIT_DEFAULTS On
PerlModule Apache2::Resource
