I'm running squid 3.2.4 with the errno patch.
My squid.conf has the following for cache_dir lines:
cache_dir rock /cache/rock-1k 128 min-size=0 max-size=1008
cache_dir rock /cache/rock-2k 128 min-size=1009 max-size=2032
cache_dir rock /cache/rock-4k 128 min-size=2033 max-size=4080
cache_dir rock /cache/rock-8k 160 min-size=4081 max-size=8176
cache_dir rock /cache/rock-16k 180 min-size=8177 max-size=16368
cache_dir rock /cache/rock-30k 300 min-size=16369 max-size=30704
cache_dir aufs /cache/aufs 3072 15 253 min-size=30705 max-size=200000000
It all seems to be working, until I do a "squid -k reconfig". After that, the
cachemgr.cgi application starts reporting zeros for the "rock" directories.
The output looks like:

I do see TCP_HIT:HIER_NONE messages in the access.log file for files that
should be stored in the "rock" directory:
10.17.17.147 - - [10/Dec/2012:16:24:34.246 -0500] "GET http://conn.skype.com/
HTTP/1.0" 200 585 TCP_HIT:HIER_NONE
but cachemgr.cgi's "Store Directory Stats" report that nothing is cached in the
"rock" directories. If I stop and restart squid cachemgr.cgi starts displaying
data for the "rock" directories. A "squid -k reconfig" later and the reports
are empty again.
Has anyone seen this problem?
