Apache24 lots of errors

Something is crashing an Apache child process every 10 seconds.

You'll have to keep bumping up the logging until you can find out what that is.

What did you do around October 21nd? Any updates?

If you rebuilt e.g. Apache for updates around then, did you rebuild anything it relies on (e.g. are you using ports OpenSSL? PHP? Any other modules?).

Tried re-starting Apache? The machine itself?

Got a test system that you can have the same set-up and see if you can reproduce the issue there.
 
Sorry i first said ports, but i meanth pkg tree, .. anyways I automatically upgrade pkg daily. I do keep cron mail log but not for that long and I only noticed because I was checking for log4j problems.
 
Set logging to debug:

I know what is causing it but not why.

Haproxy is the cause

Code: 
backend node_xxx
        timeout check 5s
        timeout connect 30s
        timeout server 120s

        option http-server-close

        mode http
        server xxx xxx.xxx.net:443 check ssl verify none
 
Is your Apache configured to use SSL and does it have a certificate configured? It seems to look for one but then fail. If you have configured certificates make sure they are in the right format and have the correct permissions (so the www user can actually read them).
