New format? The format is the same.. unless you use the new concurrency
option..

There is no change needed at all when upgrading. You may even use the
old squid.conf directive name, but support for that may eventually go
away..

You can find up to date hyperlinked squid.conf reference manuals for 2.6
and 3.0 from www.squid-cache.org. Just go to download directory and
you'll find the config manual link at the bottom of each release..

There should be messages before that telling what happened. Go up to the
first warning about the helper exiting, then see if there is any error
before that indicating why it exited..

And you can run the helper from the command line as your
cache_effective_user? And it keeps running if typing a typical request
to it?

-X only enables full debugging while parsing the configuration. To have
full debugging while it's running you need to set the debug_options
directive.
