Could it be some php functions disabled? Its just our forums that have the issue. The joomla domains are all fine when it happens, so it rules out SQL. I upped php, http and mysql versions and its better, but it still does it.

Something is stalling but not in a error generating way.

I wonder if there might be some setting in the forum conf that does something unusual? Maybe some sort of cache thing?

I noticed you had loads of failed connection attempts to mysql in that statistics page you posted. That seems strange, but when you posted about the proxy thing for https I thought maybe that was the problem. But maybe not.

I ended up building php, mysql and httpd from upstream. I stayed with mysql 5.1, but bumped them all along lots of versions.

It's certainly way improved. So leads me to think it's still either php or httpd or certainly settings in there. Maybe with php it's got something disabled that is causing it, I might try enabling all he php functions again and see if it helps.
