See > http://bugs.squid-cache.org/show_bug.cgi?id=3068 pardon me, but I don't see anything that would take 2-3 times more than configured limit and/or what squid says: squid2: 363520856 /squid/ Maximum Swap Size : 307200000 KB Current Store Swap Size: 275852960 KB squid3: 343399160 /squid/ Maximum Swap Size : 307200000 KB Current Store Swap Size: 260064224 KB squid4: 356593016 /squid/ Maximum Swap Size : 307200000 KB Current Store Swap Size: 276444512 KB that's about 30% more used than configuration option says. that could be result of filesystem overhead. > >> Note that sizeof(int) is 4 in both 32bit and 64bit compilation models. > >> I believe that blks * fs.blksize overflows 32bit before it is right > >> shifted by 10 bits. > > > > if you want to use filesizes over 2GB on 32bit system, you must make your > > program to be 64-bit capable, and compile it that way. > > > > the same applies about using 64bit numbers. > > No, "int"s are still 32bit in the 64bit compilation model.
