In module procps-ng-3.3.15, source skill.c, function check_proc
char buf[128];
This buffer is too small to read /proc/<pid>/stat
The code requires the whole file to be read:
len = read(fd, buf, sizeof(buf));
if (len <= 0 || (size_t)len >= sizeof(buf))
goto closure;
Fix I used is to increase to 256 bytes.
Worked for me.
