Hi chris, Apologies for the delayed response. So I have the base installation of apache 2.4 within Amazon EC2 (via these instructions: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/install-LAMP.html) which loads these modules by default, among a few others:
LoadModule access_compat_module modules/mod_access_compat.so LoadModule actions_module modules/mod_actions.so LoadModule alias_module modules/mod_alias.so LoadModule allowmethods_module modules/mod_allowmethods.so LoadModule auth_basic_module modules/mod_auth_basic.so LoadModule auth_digest_module modules/mod_auth_digest.so LoadModule authn_anon_module modules/mod_authn_anon.so LoadModule authn_core_module modules/mod_authn_core.so LoadModule authn_dbd_module modules/mod_authn_dbd.so LoadModule authn_dbm_module modules/mod_authn_dbm.so LoadModule authn_file_module modules/mod_authn_file.so LoadModule authn_socache_module modules/mod_authn_socache.so LoadModule authz_core_module modules/mod_authz_core.so LoadModule authz_dbd_module modules/mod_authz_dbd.so LoadModule authz_dbm_module modules/mod_authz_dbm.so LoadModule authz_groupfile_module modules/mod_authz_groupfile.so LoadModule authz_host_module modules/mod_authz_host.so LoadModule authz_owner_module modules/mod_authz_owner.so LoadModule authz_user_module modules/mod_authz_user.so LoadModule autoindex_module modules/mod_autoindex.so LoadModule cache_module modules/mod_cache.so LoadModule cache_disk_module modules/mod_cache_disk.so LoadModule cache_socache_module modules/mod_cache_socache.so LoadModule data_module modules/mod_data.so LoadModule dbd_module modules/mod_dbd.so LoadModule deflate_module modules/mod_deflate.so LoadModule dir_module modules/mod_dir.so LoadModule dumpio_module modules/mod_dumpio.so LoadModule echo_module modules/mod_echo.so LoadModule env_module modules/mod_env.so LoadModule expires_module modules/mod_expires.so LoadModule ext_filter_module modules/mod_ext_filter.so LoadModule filter_module modules/mod_filter.so LoadModule headers_module modules/mod_headers.so LoadModule include_module modules/mod_include.so LoadModule info_module modules/mod_info.so LoadModule log_config_module modules/mod_log_config.so LoadModule logio_module modules/mod_logio.so LoadModule macro_module modules/mod_macro.so LoadModule mime_magic_module modules/mod_mime_magic.so LoadModule mime_module modules/mod_mime.so LoadModule negotiation_module modules/mod_negotiation.so LoadModule remoteip_module modules/mod_remoteip.so LoadModule reqtimeout_module modules/mod_reqtimeout.so LoadModule request_module modules/mod_request.so LoadModule rewrite_module modules/mod_rewrite.so LoadModule setenvif_module modules/mod_setenvif.so LoadModule slotmem_plain_module modules/mod_slotmem_plain.so LoadModule slotmem_shm_module modules/mod_slotmem_shm.so LoadModule socache_dbm_module modules/mod_socache_dbm.so LoadModule socache_memcache_module modules/mod_socache_memcache.so LoadModule socache_shmcb_module modules/mod_socache_shmcb.so LoadModule status_module modules/mod_status.so LoadModule substitute_module modules/mod_substitute.so LoadModule suexec_module modules/mod_suexec.so # This module will cause Apache to fail to load if there is no DNS # LoadModule unique_id_module modules/mod_unique_id.so LoadModule unixd_module modules/mod_unixd.so LoadModule userdir_module modules/mod_userdir.so LoadModule version_module modules/mod_version.so LoadModule vhost_alias_module modules/mod_vhost_alias.so LoadModule watchdog_module modules/mod_watchdog.so It is using *MPM_Prefork* by default, with default values (nothing specified). I could setup a phpinfo page privately if you'd like as well. I have requested repeatedly to Amazon to put out a page that is more comprehensive than their basic MPM tuning page <https://aws.amazon.com/premiumsupport/knowledge-center/ec2-apache-memory-tuning/>, for following the instructions does not fix it. Ironically the server grinds to a halt even if no requests are being made to it. IMHO, even with the default installation Apache eats up too much memory. It would be MUCH simpler if there was a MAX_MEMORY_PERCENT directive you can place in httpd.conf, which specifies the percentage of free memory Apache is allowed to consume. Any thoughts?
