I tried to upgrade from apache 2.0.51 to 2.0.63 but it crashes as soon as new version is started and httpd is reloaded. here is a part of the log [Fri Apr 25 10:57:46 2008] [notice] Apache/2.0.63 (Unix) configured -- resuming normal operations Segmentation Fault in 3642, waiting for debugger Segmentation Fault in 3697, waiting for debugger Segmentation Fault in 3696, waiting for debugger [Fri Apr 25 10:58:11 2008] [notice] caught SIGTERM, shutting down [Fri Apr 25 10:58:22 2008] [notice] suEXEC mechanism enabled (wrapper: /usr/sbin/suexec) [Fri Apr 25 10:58:22 2008] [notice] mod_security/1.9.4 configured [Fri Apr 25 10:58:22 2008] [notice] Digest: generating secret for digest authentication ...

Upgrade is performed by the support people. If you guys can help please explain in lame terms Let me know if you need some specific info about the system. I was suggested that some modules might not be upgraded yet and they cause the crash, so to fix I should remove modules one by one from httpd config until get to the problematic one.

It's hard to say if it's a module issue, but I would say it's less likely as Apache appears to load (Apache/2.0.63 (Unix) configured -- resuming normal operations) but then the child processes all segmentation fault. How much RAM does your VPS have, and given how many processes are failing is your web server very busy? I'm wondering if it's being flooded with traffic as soon as it comes back online, hitting your VPS memory limit and being killed off ... or something else to that effect?

Pat thanks for the reply I am currently on dual 3.06 Gb with 2Gb (512Mb guaranteed) The site has 6000 uniques daily, there is 5-20 visitors all the time. In addition to main site I am running 1 relatively active phpbb forum on the same server. Mysql is pretty busy. After 2.0.63 failing to start the server is reverted back to 2.0.51 and everything runs ok.

you can do this run apachectl configtest to test the config file and it will tell you if this is a module error or a problem with apache. then so strace /etc/init.d/httpd start that will do an strace that will give you a lot of data that you can then analyze to see if there are some issues that make apache crash. paste the strace result and maybe we can help you figure this out.

For immediate fix i will suggest to rollback apache to your previous known version, this will way your sites will be online. Later upgrade it to the latest version step by step.

thanks for the reply guys I will do what is suggested by tepezcuintle. @ Srv24x7: apache is at 0.51 version right now, it appears to be the only one stable
