There appear to be some httpd processes spinning on cpu on ajax. Attaching with gdb and asking for a backtrace gives me something
like this:

Could you send us the URL that raised the problem ? We don't see
anything that could be wrong in the mbox_wrap_text code :(

This URL seems to give the problem:

There are no spinning httpds on ajax at the moment -- they seem to come and go. I suspect that they are not permanently spinning, but rather are dying whenever the client gives up on waiting. Connecting to the above URL gives me instant 100% CPU usage on the server that lasts until I hit "stop" on the browser. I get no content from the server.

I would debug further, but that would involve actually looking at the code, which I have so far managed to avoid ;-)

I forced a core dump and put it in /raid1/httpd-cores/core.31834 on ajax.

Here's the basics:
