When I start apache2 ('apachectl2 start'), this appears in /var/log/apache2/error_log:

[Mon Oct 27 12:28:26 2014] [warn] Init: Session Cache is not configured [hint: SSLSessionCache]
[Mon Oct 27 12:28:39 2014] [notice] Digest: generating secret for digest authentication ...

and 'ps -a | grep httpd2' gives (a similar call displayed 6 times):

     5644    6064    6064       5644  ?       1001 12:31:13 /usr/sbin/httpd2
     6064       1    6064       6064  ?       1001 12:31:11 /usr/sbin/httpd2
     3084    6064    6064       3084  ?       1001 12:31:13 /usr/sbin/httpd2
     5204    6064    6064       5204  ?       1001 12:31:12 /usr/sbin/httpd2

     4388    6064    6064       4388  ?       1001 12:31:13 /usr/sbin/httpd2

When I stop apache2 ('apachectl2 stop'), this appears in /var/log/apache2/error_log:

[Mon Oct 27 12:29:24 2014] [notice] caught SIGTERM, shutting down
[Mon Oct 27 12:29:25 2014] [notice] seg fault or similar nasty error detected in the parent process

Because I use postgresql, I get 6 similar calls once I start it ('pg_ctl start -D /usr/share/postgresql/data -l /usr/share/postgresql/data/pgsql.log'):

$ ps -a | grep postgres
     4580    5064    4580       4580  ?       1001 12:31:31 /usr/sbin/postgres
     5064       1    5968       6056  pty0    1001 12:31:30 /usr/sbin/postgres
     3300    5064    3300       3300  ?       1001 12:31:31 /usr/sbin/postgres
     2480    5064    2480       2480  ?       1001 12:31:31 /usr/sbin/postgres
     4540    5064    4540       4540  ?       1001 12:31:31 /usr/sbin/postgres
     5552    5064    5552       5552  ?       1001 12:31:31 /usr/sbin/postgres

I have two questions:
1. The "seg fault or similar nasty error detected in the parent process" message represents a problem? if yes, how do I solve it?
2. Why ps -a displays 6 times a similar call with httpd2 and postgres? is that the normal behavior?

Thanks,

Gery

postgres (and I assume also apache) runs multiple instance of the demon 
to improve responsiveness to multiple requests

Yes, it represent a problem. Either in signal handling or the application
itself.

That's how Apache works in prefork mode. No idea about postgres, but likely
the case is the same.

Thanks Andrey and Marco, how can I solve "seg fault or similar nasty error detected in the parent process" error?
