Aside from the fact that this one is an old version (below), it's a little distressing to see squid occasionally filling up a 1024M partition when configured for: cache_dir aufs /mnt/squid 950 32 384 It's the only thing using the partition, and sometimes squid clears it out itself within a few minutes. These log messages were seen around once occurance of this, but not sure if it was before it filled, or coming back: /var/log/squid/cache.log:2007/12/20 13:09:03| Reconfiguring Squid Cache (version 2.5.STABLE11)... /var/log/squid/cache.log:2007/12/20 13:09:03| Cache dir '/mnt/squid' size changed to 972800 KB What cases cause squid to resize an aufs store differently than it's configured value? -neil
