Hi,
I think I'm seeing a continuously rising usage of kmalloc-2048 slabs in
/proc/slabinfo and slabtop. Before I rebooted from 4.19rc3 to 4.19rc5, I
had about 4.5GB of kmalloc-2048 after about 13d8h uptime.
Now, after almost 10 minutes uptime, it has already grown to 4MB:
2166 2166 100% 2.00K 1083 2 4332K kmalloc-2048
How can I debug this? The usage started to increase immediately after
boot into an idle XFCE desktop, running a small X11 application (gkrellm
system monitor) via SSH on a remote machine
After disabling networking in NetworkManager, kmalloc-2048 usage went
down (from about ~2500 objects to 2388 active objects right now), now on
a stable, lightly fluctuating level.
This is a Lenovo Thinkpad T420, Core i5-2520M CPU, 8GB RAM, Intel
Centrino Advanced-N 6205 [Taylor Peak] WIFI module, Ethernet unused.
Once I know how to find out more details, I'm ready to report this
upstream ;-)
Thanks,
Stefan
