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 -- Stefan Seyfried "For a successful technology, reality must take precedence over public relations, for nature cannot be fooled." -- Richard Feynman -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
