[Privoxy-users] Log format

[U.Mutlu]

Hi,
I'm running privoxy from the Debian repo on a Debian 8 box, ie.:
$ dpkg -l | grep -i privoxy
ii  privoxy  3.0.21-7+deb8u1  amd64  Privacy enhancing HTTP Proxy

Here is an excerpt from the logfile /var/log/privoxy/logfile:

2020-07-13 03:40:04.264 7fdd4cff9700 Crunch: Connection failure: 
android.clients.google.com:443
2020-07-13 03:43:59.317 7fdd6d5cf700 Crunch: Connection failure: 
mtalk.google.com:5228

My machines (PC, Laptop, router) are running 24/7, but I do block
some companies via their IP blocks (for example google.com, amazon.com,
akamai.com, facebook.com, microsoft.com, opera.com) at IP level in the
firewall on the router, and open it only on demand. So, when I go to bed
I do block these. That's also the reason why the above connection attempts 
failed. That's good.

Questions regarding the above log entries:

1) What does the 3rd column ("7fdd...") mean?
Is it the source IP where the connection request came from?
That would be useful, especially if also the PID/UID etc. is encoded in it.

2) What does "Crunch" mean in this context?

3) How can I find out which application(s) made these connection attempts?
As said it's a laptop running Debian 8, so I wonder why android/google
is involved here. I have also the web browser google chrome installed,
but it wasn't running at the time of the above log entries.
