Error description
The fuser command may stuck in an endless loop. Using truss -p <fuser PID> will show that fuser is working on the same files over and over again. Example: getdirent(3, 0x000000012BD1E890, 1024) = 816 <snip> statx("/proc/10223694/fd/106",...) statfs("/proc/10223694/fd/106",...) statx("/proc/10223694/fd/109",...) statfs("/proc/10223694/fd/109",...) getdirent(3, 0x000000012BD1E890, 1024) = 1008 statx("/proc/10223694/fd/0",...) statfs("/proc/10223694/fd/0",...) statx("/proc/10223694/fd/1",...) statfs("/proc/10223694/fd/1",...) <snap> statx("/proc/10223694/fd/106",...) statfs("/proc/10223694/fd/106",...) statx("/proc/10223694/fd/109",...) statfs("/proc/10223694/fd/109",...) getdirent(3, 0x000000012BD1E890, 1024) = 1008 statx("/proc/10223694/fd/0",...) <snip> In this case the command procfiles 10223694 will loop as well.
Local fix
For the fuser command: export FUSER_VERSION=1 run the command/script executing fuser unset FUSER_VERSION No workaround for procfiles.
Problem summary
fuser/procfiles command may stuck up with endless loop
Problem conclusion
offset caluclation is changed in such a way that it is dependent on the last filename that was returned.
Temporary fix
