Ever since I upgraded to Linux 5.10 (from 5.4), I am frequently, but not always, getting random failures from pkill/pgrep (anything that uses pgreps grep functionality): > pkill: cannot allocate 4611686018427387903 bytes I traced this back to this fix upstream, which has not made it into a release yet: https://gitlab.com/procps-ng/procps/-/commit/bb96fc42956c9ed926a1b958ab715f8b4a663dec Adding that patch to my user patches resolves the issue. Since the next release might still be a while away, and then won't be instantly stabilized, backporting that patch might be a good idea for users of newer kernels.
