I am running 64bit build of squid on 64bit system. The output of top/ps shows that squid is using as much memory as claimed in report. I configure cache directory with size of 4T: cache_dir ufs PATH 4194304 128 256. There are many child-process start, following is output of `ps`: USER 20401 0.0 0.0 71020 2728 ? Ss Feb14 0:00 /PATH/TO/squid -f /PATH/TO/CONFIG/FILE -n squidHot USER 20405 0.5 11.8 8258832 7771408 ? S Feb14 1298:30 (squid-1) --kid squid-1 -f /PATH/TO/CONFIG/FILE -n squidHot USER 20440 0.0 0.0 29468 1444 ? S Feb14 0:16 (logfile-daemon) /PATH/TO/access.log USER 20441 0.0 0.0 29460 1256 ?

Other part of report also make me puzzled: Internal Data Structures: 1185 StoreEntries 1184 StoreEntries with MemObjects 8 Hot Object Cache Items 9 on-disk objects `9 on-disk objects` means only 9 entries of 1185 are stored on disk, and others are stored in memory?

And why? -- Sent from: http://squid-web-proxy-cache.1019090.n4.nabble.com/Squid-Users-f1019091.html _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
