Running slocate allocates many entries in the dentry and inode caches,
which are accounted for in the Slab: line of /proc/meminfo.

libgtop2's glibtop_get_mem_s () computes "user" memory as
  MemTotal: - MemFree: - Cached: - Buffer:
(using the /proc/meminfo terminology), which means that the dentry cache
is accounted for as "user" memory.

I'm not quite sure whether just subtracting Slab: from "user" memory is
good enough (some of the memory allocated as Slab: is directly caused
by user-space actions, e.g. opening a file, creating a process), but
I think it still would be an improvement. More detail is available in
/proc/slabinfo if necesary.

Comment 3 Matthew Miller 2006-07-10 20:25:33 UTC
Fedora Core 3 is now maintained by the Fedora Legacy project for security
updates only. If this problem is a security issue, please reopen and
reassign to the Fedora Legacy product. If it is not a security issue and
hasn't been resolved in the current FC5 updates or in the FC6 test
release, reopen and change the version to match.

Thank you!
