Yocto in Docker yields pseudo inode errors - docker

Question

We are currently building an embedded Linux OS using Yocto inside an Docker container. All persistent directories are mounted as volumes.
This is accomplished by generating an conf/site.conf setting those directories:
DL_DIR="/artifacts/downloads"
TMPDIR="/artifacts/tmp"
SSTATE_DIR="/artifacts/sstate_cache"
PERSISTENT_DIR="/artifacts/persistent"
DEPLOY_DIR_IMAGE="/images"
DEPLOY_DIR_IPK="/ipk"
And therefore running the image with
docker run --rm \
-v /opt/yocto/projectname:/artifacts \
-v /opt/deploy/projectname/ipk:/ipk \
-v /opt/deploy/projectname/images:/images \
-it <container>
All of this is working fine, the output is deployed as expected and everything works great.
However, upon rebuilding various recipes due to updates, we see yoctos pseudo build-environment abort()ing frequently. Most of the time its an rm or an tar command being killed.
Almost all errors are ino path mismatches like
path mismatch [1 link]: ino 23204894 db '/ipk/aarch64/glibc-charmap-jis-c6229-1984-a_2.35-r0_aarch64.ipk' req '/ipk/aarch64/locale-base-is-is_2.35-r0.1_aarch64.ipk'.
dir err : 107508467 ['/artifacts/tmp/work/aarch64-agl-linux/glibc-locale/2.35-r0/packages-split/glibc-binary-localedata-nb-no.iso-8859-1/CONTROL'] (db '/artifacts/tmp/work/aarch64-agl-linux/glibc-locale/2.35-r0/packages-split/glibc-binary-localedata-sgs-lt/CONTROL/control') db mode 0100644, header mode 040755 (unlinking db)
Child process exit status 4: lock_held
Couldn't obtain lock: Resource temporarily unavailable.
lock already held by existing pid 3365057.
(I appended the error logs of the this example at the end of this post)
or just plain
path mismatch [1 link]: ino 23200106 db '/ipk/aarch64/libcap-ng-doc_0.8.2-r0_aarch64.ipk' req '/ipk/aarch64/libcap-ng-doc_0.8.2-r0.1_aarch64.ipk'.
Setup complete, sending SIGUSR1 to pid 2167709.
When we were building the same project natively without docker, we never have seen errors like this. So we assume there are some compatibility issues with docker and pseudo. We already tried dockers devicemapper and overlay2 storage drivers.
The current workaround is to delete those affected files manually. But this mostly leads to other problems down the line.
We are out of ideas where to look in solving the problem. No yocto resources regarding pseudo-errors were of any help.
Is there any hint to debug those errors in a meaningful way or do we have to refactor the docker builds somehow to prevent those pseudo-errors?
