Kernel memory leak in version 004
vojtad opened this issue · 1 comments
We've upgraded to 004 version a month ago and since that upgrade we've seen a lot of weird memory issues.
After weeks of debugging I am sure it is because of 004 version. When I downgraded to 003 all went back to normal.
These memory issues caused kernel dynamic memory reported by smem -w to grow steadily. In the end the server always froze completely because OOM killer was not able to kill any process to free memory. Unfortunately, I have no more debug details from kernel since I am not able to compile custom kernel on this server.
We are running Debian Buster with this kernel:
$ uname -a
Linux starkiller 4.19.0-12-amd64 #1 SMP Debian 4.19.152-1 (2020-10-18) x86_64 GNU/Linux
I've also tried upgrading kernel from Debian Buster backports but it didn't help.
Our network card details from lspci:
09:00.0 Ethernet controller: Tehuti Networks Ltd. TN9510 10GBase-T/NBASE-T Ethernet Adapter
Subsystem: Tehuti Networks Ltd. Ethernet Adapter

I had the same issue with the pex10000sfp card on the Ubuntu version 20.04.
There is a pull request to the 003 branch to solve kernel error below : #44
