Niltze [Hello], Ed-
I have recently experienced memory not being released, and
consequently, crashes with the referenced subject being output.
This issue seems to have an affinity to the Google Compute Engine (GCE)
KVM virtualization -based cloud fabric -- where I run/test most of my
Debian -based kernels. It has occurred with reiser4 -enabled kernels
5.10.29 and 5.10.48 built with GCC10 for Debian Bulleye.
Whereas I built those kernels in a bare metal AMD Epyc reiser4 SFRN
4.0.2 environment with 128Gb of RAM and running either of the above
kernels and/or 5.10.42:
< https://metztli.it/bullseye/moiocoiani.png >
I did not experience any issues in the bare metal unit while building
the kernels.
Notwithstanding, utilizing the kernel cloud versions generated for
those kernels referenced above in Debian upcoming Bullseye cloud
instances hosted in GCE seem to swallow the memory and eventually crash
during sustained operations, like SSH incoming 17 Gig data and/or unTAR
12 Gb archive, etc. Indeed, in these cloud instances the memory is
modest -- like 6Gb and/or 16Gb RAM; yet, it should not happen. (see
attached GPFs sections).
Recently I have seen similar GPFs reports in the Linux mailing list --
where users are obviously not using reiser4 -- and thought there might
be a relation.
Best Professional Regards.
P.S. I am patching to enable 'kernel read' on reiser4 -based Debian
netboot installer; including your reiser4 SFRN 4.0.2 modified patch for
5.10.47 kernels and JFS 5.11 for 5.10.xy patches (included)
