I'll tell you about the current environment as it stands. We are running an Online Enrollment System using Apache2 & PHP5 on five Windows servers and Sybase on a UNIX machine.
Four of the webservers are external facing and load balanced. The other is used internally only.
In addition to the web service each of the web servers also run another separate java service on port 8080.
The issue we are having is that intermittently, the login page for the internal interface of the enrollment system does not render but other pages do! This means that when it happened users were ok if they were already logged in, but could do nothing if they weren't. This was initially only happening on one of the external servers however it is now happening on the internal server.
Rebooting the machine always seems to fix it, however we would like to get to the bottom of the problem.
The code in the login script is very simple and mostly basic HTML, however we noticed that when we remove all the code between the 'body' tags, the page will render correctly. Therefore we thought that there may be a special character somewhere on the page. However it doesn't really explain why it fixes itself after a reboot and why none of the other servers are experiencing this?
Any advice would be appreciated.
Thanks,
Tamaki
