Some applications (Kubernetes/Docker) create rather long lines in /proc/mounts, and libhugetlbfs emits an error when it attempts to read one of lines with a size greater than 2048.
See the method find_mounts starting near line 619 in hugeutils.c (https://github.com/libhugetlbfs/libhugetlbfs/blob/master/hugeutils.c#L619).
Error message: libhugetlbfs: ERROR: Line too long when parsing mounts
From strace of the process emitting that error:
read(3, "overlay /var/lib/docker/overlay2"..., 2048) = 2048
write(2, "libhugetlbfs", 12) = 12
write(2, ": ERROR: Line too long when pars"..., 43) = 43
close(3) = 0
Example line:
