squid workers and logfiles: cache_kid0.log?

["Rietzler, Markus \(RZF, SG 324 / <RIETZLER_SOFTWARE>\)" <markus.rietzler@xxxxxxxxx>]

when i use workers 2 and 

access_log daemon:/squid/logs/access_kid${process_number}.log squid
cache_log /squid/logs/cache_kid${process_number}.log

I get

access_kid1.log
access_kid2.log
access_kid3.log

and 

cache_kid0.log
cache_kid1.log
cache_kid2.log
cache_kid3.log

kid3 is coordinator. so access_kid3.log is empty, which is ok for coordinator.
what is cache_kid0.log? this file is empty.
