We are experiencing the same issue. Fresh install of Ubuntu 10.10LTS
with default apache2, mysql, php. I can say for certain that it's not a
hardware issue. This is a virtual server running on an ESX host. Let
me know if there are any other details I can pull to help with this
issue. This is a production server and it crashes with this OOM about
once a week.
Apache2 Loaded Modules:
core mod_log_config mod_logio prefork http_core mod_so mod_alias mod_auth_basic
mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host
mod_authz_user mod_autoindex mod_cgi mod_deflate mod_dir mod_env mod_mime
mod_negotiation mod_php5 mod_reqtimeout mod_rewrite mod_setenvif mod_status
PHP Version: 5.3.3-1ubuntu9.5
The default also came with Suhosin Patch 0.9.9.1.
