Re: [PHP] Exception thrown without a stack frame

I'm getting exceptions thrown without a stackframe. I understand what this
means but not how it can happen given the following:

1. *every* frontend script on the site is wrapped in a try/catch block
2. I have set an exception handler to dump these so-called uncaught exceptions
in the error log

I use APC on the site/server in question but it doesn't matter whether I actually
load or use APC as to whether these uncaught exceptions occur.

I can't seem to reproduce the problem from my own browser - although it's
difficult to determine much from the log given the lack of information in any
entry referring to 'exception thrown without a stack frame' - apparently the
uncaught exception is not causing users to see broken or blank pages.

The problem only occurs on the production server, I can't reproduce it
on my test server no matter how hard I push with ab.

I haven't updated php for quite a long time which is at version 5.1.1

has anyone ever experienced something like this? anyone have any clue as to
what it might be.

Maybe you can see the timestamp of when the exception was thrown and
match that in your server logs to get a better idea of what page the
user was hitting?
