Apache2::Resource uses the
BSD::Resource module, which uses the C
setrlimit to set limits on system resources such as memory
and cpu usage.
RLIMIT operation available to limit on your system can be set
by defining that operation as an environment variable with a
prefix. See your system
setrlimit manpage for available resources
which can be limited.
The following limit values are in megabytes:
MEMLOCK; all others are treated as
their natural unit.
If the value of the variable is of the form
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:
