Recently my site (an https connection, running on an Amazon EC2 ubuntu apache2.2) has this issue where I need to load the page several times (3-4) before it will load normally without issue. It will then load normally as long as I keep loading pages regularly (every couple seconds). It will stall again if I don't load pages for a few minutes.
It has nothing to do with my application because I don't have this problem with the exact same app codebase on my Apache installation on my laptop.
The only things to my knowledge that I've changed is that I recently installed mod_spdy and then a few weeks later I installed mod_pagespeed, https://developers.google.com/speed/pagespeed/mod. However, I have since turned mod_pagespeed off by setting its pagespeed.conf to mod_pagespeed off
. Unfortunately, that didn't solve the problem.
The line below is how every of last 10 lines of my error.log look:
# tail -f /var/log/apache2/error.log
