From your use of client_dst_passthru I assume you have this Squid configured as a transparent interception proxy?

This is apache format for web end-servers. Do you have anything in Squid format which has better logging information for proxy details?
Any cache.log traces of LIVE/DEAD status on the peer and indication of how that interacts with the access.log timing? It could simply be the peer going unavailable for a while.
This issue was also present in 3.2.0.19 and 3.2.0.20. Are there any configuration options I may be missing? I've had this working before, in Squid 3.2.0.16 and Squid 3.2.0.17, with the options detailed above. Thanks, Nathan.
