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.
Have you had time to look into this? /me willing to test
Yes, we have a tentative fix for this - some testing would be really useful, I'll build some packages.
OK, can you try the packages here: http://people.redhat.com/jorton/Taroon-httpd/ feedback gratefully received!
Giving it a try now.
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!
more misc info: running httpd, mod_ssl and php, no mod_{python,perl,etc}
Any idea on when this will be pushed to up2date?
It's scheduled for inclusion in the next update. Thanks for the report and testing!
httpd-2.0.46-26.ent ? yes
Yes indeed, -26.ent has the fix and is included in the Update 1 Beta.
