Apache2::Resource - Limit resources used by httpd children
PerlModule Apache2::Resource
# set child memory limit in megabytes
# default is 64 Meg
PerlSetEnv PERL_RLIMIT_DATA 32:48
# linux does not honor RLIMIT_DATA
# RLIMIT_AS (address space) will work to limit the size of a process
PerlSetEnv PERL_RLIMIT_AS 32:48
# set child cpu limit in seconds
# default is 360 seconds
PerlSetEnv PERL_RLIMIT_CPU 120
PerlChildInitHandler Apache2::Resource
"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.
To set reasonable defaults for all RLIMITs, add this to your httpd.conf:
PerlSetEnv PERL_RLIMIT_DEFAULTS On
PerlModule Apache2::Resource
BSD::Resource(3),
setrlimit(2)
