Dev,
This is a strange one. After updates on 11/23, httpd began segfaulting -- repeatedly:
l /var/log/httpd/error_log* -rw-r--r-- 1 root root 24306171 Nov 24 14:48 /var/log/httpd/error_log -rw-r--r-- 1 root root 625 Nov 24 00:00 /var/log/httpd/error_log.1 -rw-r--r-- 1 root root 1742 Nov 21 13:19 /var/log/httpd/error_log.2 -rw-r--r-- 1 root root 504 Nov 10 00:00 /var/log/httpd/error_log.3 -rw-r--r-- 1 root root 1754 Nov 3 00:00 /var/log/httpd/error_log.4
I have a second server that confirms this exact same behavior:
l /var/log/httpd/error_log* -rw-r--r-- 1 root root 25049142 Nov 24 14:48 /var/log/httpd/error_log -rw-r--r-- 1 root root 1137 Nov 24 00:00 /var/log/httpd/error_log.1 -rw-r--r-- 1 root root 1752 Nov 17 00:01 /var/log/httpd/error_log.2 -rw-r--r-- 1 root root 504 Nov 10 00:00 /var/log/httpd/error_log.3 -rw-r--r-- 1 root root 1754 Nov 3 00:01 /var/log/httpd/error_log.4
The log file size jumped from 625 bytes to 24306171 bytes (1137->25049142 on the other server) in just a matter of hours. The old log contains, in its entirety:
