We had a problem on our system when the filesystem holding /tmp
was short of room.
I discovered that findfile was creating a temporary file in /tmp
containing the matched filenames. When this list was large and file
filesystem containg /tmp didn't have room to hold it a truncated list
of filenames was returned. There was no error indication.
The number of matched files also varied with how much space was
available in /tmp.
Have a look and see how much space is left in /tmp.
Or was it /var/tmp? Now I'm not sure which it was...
Check both, it was one of the two.
