Hello all,
It seems that OpenAFS 1.8.x uses more slab (or doesn't free it as
quickly) than 1.6.20 .
The machine in question uses AFS heavily. it is used to backup our
AFS area. It scans through files constantly and in more than directory
and in two domains at a time.
I recently upgraded from Debian Stretch running openafs 1.6.20 to
Debian Buster 1.8.2. After encountering the problem I also tried Debian
Bullseye (testing) with openafs 1.8.6. Same symptoms.
On a 6GB (virtual) machine it used enough to start swapping and kill
the machine.
The last output of 'slabtop' says:
OBJS ACTIVE USE OBJSIZE SLABS OBJ/SLAB CACHE SIZE NAME
5235885 5235885 100% 1.06K 539811 15 8636976K afs_inode_cache
Any way to change this behavior?
Thanks!
Cahd.
