Could it be that your server filesystem gets corrupted? Maybe it's a
good idea to make backups and then run a thorough check...

did you check the file modification data?

No, caching does not touch any files, caching only happens in memory.
And the JSPs in the filesystem should only be re-generated, if they have
changed

You could write a script that touches all files which are not currently
locked so that you can re-publish them.
You can do this in a separate project, so that you can publish that
complete project without publishing anybody's ongoing work. (The same
set of files can be assigned to more than one project. Whenever a file
is changed, it is held by that project from which it was changed last.)

I had posted a JSP which touches *all* files in a folder tree without
modifying their change date. I will append it again.
But this script assumes that the files in question have been locked the
files in question before executing the script. If you want to lock the
files in the script,you would have to add code for that (see javadocs
for classes CmsObject and CmsResource)

If you want to be more careful, then you could call
res.getLock().isNullLock() for each resource first. If isNullLock() 
returns true, then the resource is not currently locked by anybody and
you can safely lock and touch this resource without interfering with
anybody else's work.

My code follows below.
