Ok, so it is probably being executed as root, unless the help system is
suid root (possible, but I doubt it).

Removing that directory recursively shouldn't take but a few minutes
even if the disk is filled there.

I don't think it would take that long, but if it does, very likely it is
the nature of recursive code. A delete-like function scans for files and
directories, then enters a directory and scans for files and directories
again; so, until it finally reaches the last directory that has no more
subdirectories. Then it begins deleting the files of the last
subdirectory; it then backs out and deletes the directory itself.
Recursive delete of deep trees can take a long time, though I can't
imagine it taking 20 hours or more. I'd be tempted to use vi on some of
the files in those directories and see if they really are help files
(they should be, but for example, malicious attacks tend to hide the

If that is the last date then the problem probably is gone. Still, the
left-over needs to be removed, it must be eating up inodes by the
thousands or millions (typically something like 1 inode for every 4k or
8k bytes on the drive; you may have used up over 90% on unused 4k or 8k

If you have a nearly filled partition but only a very small space
actually accounted for, then your inodes must be nearing capacity.
Again, it sounds like a deep and complicated tree, and removal via
recursion is slow. Especially if for some reason it makes you swap out
while doing the delete.

I would have to wonder if cron is doing something with it you don't know
about. You may want to check that.

Any /tmp/susehilf.xxxxx should probably be removed without worry.
Especially old stuff dated way back in July or whenever.

Sounds like you can let loose your Terminator...kill all the
susehilf.xxxx temp stuff.
