I've put 2.6.0-test5 yesterday on a mail server and today I noticed that there was a huge amount of memory 'missing' from vmstat. So I took a look at slabinfo and found out that file_lock_cache has a huge amount of objects that won't shink down even under memory pressure. The line, as it is now, looks like: file_lock_cache 5828600 5828600 96 40 1 : tunables 120 60 \ 8 : slabdata 145715 145715 0 The whole slabinfo is attached. This is a dual Pentium III with 1Gb RAM and three SCSI disks in two Adaptec aic7896/97. I don't know if I can hold the server up for much longer so please if you want me to get any other information let me know.
