So I tried rebooting, but apache2 still will no longer start. The message in /var/log/apache2/error_log is [Fri Jun 16 18:48:32 2006] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
This message is harmless. [Fri Jun 16 18:48:32 2006] [notice] suEXEC mechanism enabled (wrapper:
/usr/sbin/suexec2)
Also probably harmless. If I do
linux:/var/log # grep httpd message I get Jun 16 18:27:32 linux kernel: httpd2-prefork[9915]: segfault at 0000000055c56f98 rip 00002aaab494d8d4 rsp 00007fffff887fb0 error 4 Jun 16 18:27:50 linux kernel: httpd2-prefork[9966]: segfault at 0000000055c56f88 rip 00002aaab494d8d4 rsp 00007fffff898dd0 error 4 Jun 16 18:30:53 linux kernel: httpd2-prefork[10059]: segfault at 0000000055c56a58 rip 00002aaab494d8d4 rsp 00007fffff8fc3a0 error 4 Jun 16 18:40:13 linux kernel: httpd2-prefork[6845]: segfault at 0000000055c56fc8 rip 00002aaab494d8d4 rsp 00007fffffb54ea0 error 4 Jun 16 18:48:18 linux kernel: httpd2-prefork[8665]: segfault at 0000000055c56f68 rip 00002aaab494d8d4 rsp 00007fffffc7bc20 error 4 Jun 16 18:48:33 linux kernel: httpd2-prefork[8697]: segfault at 0000000055c56f98 rip 00002aaab494d8d4 rsp 00007fffffd771c0 error 4
Yikes, segfaults suck. Do you see anything more specific in /var/log/apache2/error_log? Have you updated/installed any packages recently?
