It seems in some cases procs_running field of /proc/stat can contain 0 even if vmstat itself is running. At least this can be reproduced on Linux 3.9.3 compiled with BFS scheduler. Since getstat() decrements value of procs_running by 1, we get overflow: $ vmstat 1 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 667732 918996 57376 911260 21 30 36 40 98 45 14 82 4 1 4294967295 0 667728 916716 57376 911264 8 0 8 0 1958 3733 28 7 65 1 0 0 667700 915996 57376 911416 24 0 152 0 1735 3600 23 5 71 1 4294967295 0 667700 915872 57376 911392 0 0 0 0 1528 3165 21 4 76 0

HOW TO CONTRIBUTE
See Documentation/BUGS file.
PACKAGING
If you are a downstream maintainer (packager) for a Linux
distribution, please avoid causing troubles. This section
applies to you.
Avoid maintaining distribution specific patches. Send your
patches to upstream, where they are at least reviewed, if not
included.
Please forward bug reports. If your bug database is public and
busy enough to bother with, please make this known. Follow
Debian's lead in making the bug database easy to comment on via
email without need for an account.
For normal packages, ensure that you do not add debugging flags
to the CFLAGS variable.
