SYNOPSIS
PerlModule Apache::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 Apache::ResourceDESCRIPTIONApache::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 vari
able 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:
