>I'm running CentOS 5.3 with httpd-2.2.3-22.el5.centos.x86_64 and php-5.1.6-23.2.el5_3.x86_64. When the logrotate scripts run and send the HUP signal to httpd, the httpd process quits instead of reloading. The only thing I can find in the logs is this:

A follow-up, I cannot seem to reproduce this on my laptop (using i386 instead of x86_64) with the same configuration.
