See my other post: the brutal (but effective) self-defense tool I used
(back then, when NM was yet allowed on my boxes ;-) was to "chattr +i"
the file. With some luck I'd find complaints in the log files which helped
clear up which program (and in which context) was trying to do something
to the files.
The nice part of chattr is that it protects the direntry too (so the
obvious fall-back of removing and re-creating doesn't help).
