Is it possible that you have two 64.34.72.226 entries in that 
GlobalWhitelistDSTNet ACL? Perhaps in another included configuration 
file or something like that?

Squid thinks that there is more than one copy of 64.34.72.226 address in 
GlobalWhitelistDSTNet ACL. It could be Squid bug, of course. Please 
share a configuration that reproduces the issue or a pointer to 
compressed "squid -N -X -d9 ..." output while reproducing the problem.

This assert is a side effect of the above ACL problem/bug - you probably 
have many IPs in that ACL and the corresponding WARNINGs exceed Squid 
hard-coded message accumulation limit. Now that we know how a broken(*) 
configuration can produce so many early cache.log messages, we should 
probably modify Squid to quit without asserting, but let's focus on the 
root cause of your problems -- those WARNING messages.

(*) I am not implying that _your_ configuration is broken.


Cheers,

Alex.
