Ooooops, it default value is 90 :) My bad, too much nightly work :) Well. Let's read squid.conf.documented: # TAG: cache_swap_low (percent, 0-100) # The low-water mark for AUFS/UFS/diskd cache object eviction by # the cache_replacement_policy algorithm. # # Removal begins when the swap (disk) usage of a cache_dir is # above this low-water mark and attempts to maintain utilization # near the low-water mark. # # As swap utilization increases towards the high-water mark set # by cache_swap_high object eviction becomes more agressive. # # The value difference in percentages between low- and high-water # marks represent an eviction rate of 300 objects per second and # the rate continues to scale in agressiveness by multiples of # this above the high-water mark. # # Defaults are 90% and 95%. If you have a large cache, 5% could be # hundreds of MB. If this is the case you may wish to set these # numbers closer together. # # See also cache_swap_high and cache_replacement_policy Eviction starts when you cache achieves cache_swap_low. So, may be you traffic is more than squid can be replaced between 90 and 95%. So, you can try to decrease cache_swap_low. Or, review your caching policy to be less aggressive. Or, increase cache_dir limit. Or all together. > >> >> >> -- >> View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/WARNING-Disk-space-over-limit-tp4683055.html >> Sent from the Squid - Users mailing list archive at Nabble.com. >> _______________________________________________ >> squid-users mailing list >> squid-users@xxxxxxxxxxxxxxxxxxxxx >> http://lists.squid-cache.org/listinfo/squid-users >> >> _______________________________________________ >> squid-users mailing list >> squid-users@xxxxxxxxxxxxxxxxxxxxx >> http://lists.squid-cache.org/listinfo/squid-users >
