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)
