Hi all,
As the subject says, is this a know issue? I have been tracking the growth at
one second intervals and it looks like this:
512 (67716608) Slab: 606744 kB
512 (67717120) Slab: 606752 kB
512 (67717632) Slab: 606756 kB
0 (67718144) Slab: 606756 kB
512 (67718144) Slab: 606760 kB
1024 (67718656) Slab: 606768 kB
512 (67719680) Slab: 606772 kB
512 (67720192) Slab: 606776 kB
0 (67720704) Slab: 606776 kB
512 (67720704) Slab: 606780 kB
First fiels is the diff in numobj, in parentheses is actual numobj and last is
the total slab size from /proc/meminfo.
kmalloc-8 68044800 68044800 8 512 1 : tunables 0 0 0
: slabdata 132900 132900 0
dm-io slab also seems large, don't know... :
dm_io 75924 147288 40 102 1 : tunables 0 0 0 :
slabdata 1444 1444 0
Some other info about the system/kernel is attached.
