The server PHP scripts are apparently crashing whenever it receives the
*valid* X-Forwarded-For header of the type which gets emitted when you

I can also reproduce the same crash/terminate behaviour when most other
perfectly valid XFF header are sent. The web developer who authored that
site is very ignorant of how X-Forwarded-For is used.
To work around this either remove the forwarded_for directive
completely. Or set it to another value than "off".
Given the set of things that cause the server to die. You are probably
best going with truncate or delete.
