# Note about ulimits:
# if you want to set ulimits, e.g. to increase the max number of open file handle, 
# or to allow core files, you can do so by editing /etc/sysconfig/apache2 and
# simply write the ulimit commands into that file.
# Example:
# ulimit -n 16384
# ulimit -H -n 16384
# ulimit -c unlimited
# See the output of "help ulimit" in the bash, or "man 1 ulimit".
