Additional info:

actual is taroon
expected is freebsd ( for reference)


On another taroon machine

30 second timout

[Fri Sep 26 11:29:14 2003] [notice] Apache/2.0.46 (Red Hat) configured --
resuming normal operations

I looked for another example, but couldn't find it.  IIRC it was a ~2 minute
timeout.  possibley the "resuming normal operations" message happens before
connections are possible.


I left the priority/severity as normal, but since taroon/RHEL3 is designed for a
server environment ( where httpd.conf updates happen frequently and log rotation
is daily/semi-daily rather than weekly), I would recomend a higher priority.
Comment 1 Christopher McCrory 2003-10-15 16:10:55 EDT 
Have you had time to look into this?

/me willing to test
Comment 2 Joe Orton 2003-10-16 06:00:00 EDT 
Yes, we have a tentative fix for this - some testing would be really useful,
I'll build some packages.
Comment 3 Joe Orton 2003-10-16 06:57:33 EDT 
OK, can you try the packages here:

http://people.redhat.com/jorton/Taroon-httpd/

feedback gratefully received!
Comment 4 Christopher McCrory 2003-10-16 12:46:52 EDT 
Giving it a try now.
Comment 5 Christopher McCrory 2003-10-16 13:35:27 EDT 
That seems to have done the trick!
On a production server, the time was a second or two, about the same as apache 1.3.x

On a test server with ~8000 virtual hosts (yes 8000), the time to reload was
about 15 seconds.  Most of which I imagine was parsing ~35000 lines of configs.

You da' man!
Comment 6 Christopher McCrory 2003-10-16 13:36:40 EDT 
more misc info:

running httpd, mod_ssl and php, no mod_{python,perl,etc}
Comment 7 Christopher McCrory 2003-10-23 18:54:49 EDT 
Any idea on when this will be pushed to up2date?
Comment 8 Joe Orton 2003-11-12 10:29:27 EST 
It's scheduled for inclusion in the next update.  Thanks for the
report and testing!
Comment 9 Christopher McCrory 2003-12-15 16:15:54 EST 
httpd-2.0.46-26.ent ? yes
Comment 10 Joe Orton 2003-12-15 16:24:55 EST 
Yes indeed, -26.ent has the fix and is included in the Update 1 Beta.
