The Debian version is squeeze, as you can see, and the box is an HP ProLiant BL460c G6 blade with 8 cores and 32 GB RAM, so hardware resources are plenty. > Do you log PHP errors?

I see now that the PHP logging configuration was hosed when I moved the web server from one function account to the other. I will now get this sorted out and see what I can find in the error logs. If necessary I'll come back again. Thanks again!
