[Mongrel] Socket read returned insufficient data

In the several months I've been using Mongrel, I've experienced two  
crashes.  Both were immediately following a "Socket read returned  
insufficient data" error from HTTPRequest.  Both times, the mongrel  
process would hang indefinitely (and not respond to requests) untill  
manually killed.

The first instance references a line where I was using  
XML::Document.file(<external url>).  It's not clear under what  
conditions the second instance occurred.

Any ideas on why this might be happening or what can be done to  
prevent it?

Thanks.
