Subject: memory leak?
Date: 21 Jul 2002 16:00:09 +0200 [thread overview]
Message-ID: <yw1xn0sluqom.fsf@gladiusit.e.kth.se> (raw)
I noticed that doing lots or file accesses causes the used memory to
increase, *after* subtracting buffers/cache. Here is an example:
$ free
total used free shared buffers cached
Mem: 773776 30024 743752 0 1992 10424
-/+ buffers/cache: 17608 756168
Swap: 81904 0 81904
$ du > /dev/null
$ free
total used free shared buffers cached
Mem: 773776 78008 695768 0 26328 10472
-/+ buffers/cache: 41208 732568
Swap: 81904 0 81904
Here 24 MB of memory have been used up. Repeating the du seems to have
little effect. This directory has ~3200 subdirs and 13400 files.
After a few hours use about 200 MB are used, apperently for
nothing. Killing all processed and unmounting file systems doesn't
help.
Is this a memory leak? I get the same results with ext2, ext3,
reiserfs and nfs.
