regarding swapfail after i suffer alot even on latest squid v what i found is if you have lets say 32geg ram and you specify cache_mem 10 GB or whatever size you have if it reach that it start happening swap fail mostly on fast smole object like js file or jpg not more then 100k max and same problem cache_dir aufs /mnt/cache-a 500000 when you reach max specify size dose not Mather if diskd or aufs probably rock also what im trying to say is during that period wen max storage happen it start fkp reason unknown 1= replacing file last freq..used it delete from storage and it dose not delete the object info from swap.state result swap fail 2= might be write issue = saving the object info to the swap.state and it its not done on storage wen storage full it get fkp 3 = i don't know if may be if that developer guys should check on source code if the write to swap.state happen before the file get stored wish is not good it should be wen the file get stored and signal the write to swap.state to save the object detail in it not befor as i says its what my testing and experiment that i have reach to those point. i might be wrong -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Sudden-but-sustained-high-bandwidth-usage-tp4676366p4676635.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
