Hi, I encountered this really weird situation. Have a coss partition besides aufs. Did a squid -k shutdown and then, the size of the coss file increased by 1GB! I looked at cache.log, nothing unusual during shutdown. When I started Squid later, URLs with Vary objects in the coss file returned TCP_MISS. Squid was somehow unable to read the new coss file (the larger one) and hence produced TCP_MISS. Has anyone come across this kind of situation, wherein after Squid shutdown, size of the coss file increases by 1GB? Thanks.
