I upgraded the kernel version from 3.13 to 3.19 and it seems the memory leak has stopped! - I will report back if I see a leak again.

Basic system info: Linux Mint 17, thinkpad T530 with BTRFS filesystem.
Upgrading Linux Mint from 17 to 17.1 and kernel to 3.16.0-30-generic resolved that issue :)

I first observed this bug with 2.6.30-rc8, while trying to reproduce #13375. After whole night of NFS activity  system becomes very slow, i blamed mozilla first, but now i think problem is deeper, at least slabtop clearly showed constantly growing kmalloc-96, without X at all.

Current /proc/meminfo (with NFS server active)

kmalloc-96 - Memory leak in Kernel


https://www.linuxquestions.org/questions/linux-server-73/malloc-64-memory-leak-trashing-866074/
If you have Fedora 14 + HP ProLiant DL360 G7 X5650 2P or similar and you have the above issue, add teh following to grub.conf kernel line and it will possibly fix this for you:

apm=off acpi=off

But... as for WHY APM and ACPI tangles with this particular Proliant... I have no clue.

Hope this helps someone.

Thanks. Both of you have very good usage of kmalloc-96. Interestingly both with BWDPI off..

下面的配置说明是好的。

    Is the issue present using linux 4.17.14.arch1-1?

No it wasn't.

After reverting back to 4.18+ I am still experiencing the memory leak. After a lot of experimentation, the leak still remains. I am still not sure which module is causing it. Could anyoune share their thoughts on what should be done next. I really don't want to switch to lts since my wifi does not work properly on it. I am thinking of building kedr on my system. Is there a better alternative?
