[squid-users] store.log is growing HUGE

Hi All!

I'm running 3 squid hosts (not siblings, just dns round robin), all 3
have the same config file (i mean absolutely no difference).
But while two of them are running smoothly, 3rd have a problem -
although it is serving requests normally, its store.log file is growing
by approx. 1Mb/sec. File mostly consists of lines like:

1287820122.900 RELEASE -1 FFFFFFFF AFA36A32B9A4BE25DF197B156F9EDD4C
? ? ? ? ?/? ?/? ? ?
1287820122.900 RELEASE -1 FFFFFFFF B7978B41EE7BF36B5049B7D1B088B2C2
? ? ? ? ?/? ?/? ? ?
1287820122.900 RELEASE -1 FFFFFFFF C298A1D274A53F38B0FC630CE0380599
? ? ? ? ?/? ?/? ? ?

And so on, 80Gb of them (well, sometimes there's normal lines too).
Any thoughts? I made it "config_store_log none" in config for now, but
the situation is scaring me a little, those servers are running a large
project ;)
