Weird, there's nothing in Xymon that touches these files once they have
been created.

If you run "stat FILENAME" it will show you the time the permissions were
changed in the "Change:" line. E.g.

$ stat bla
  File: `bla'
  Size: 1               Blocks: 8          IO Block: 4096   regular file
Device: 6801h/26625d    Inode: 2851019     Links: 1
Access: (0644/-rw-r--r--)  Uid: ( 1000/hstoerne)   Gid: ( 1000/hstoerne)
Access: 2013-02-14 14:06:56.000000000 +0100
Modify: 2013-02-14 14:07:10.000000000 +0100
Change: 2013-02-14 14:07:10.000000000 +0100

$ chmod 400 bla

$ stat bla
  File: `bla'
  Size: 1               Blocks: 8          IO Block: 4096   regular file
Device: 6801h/26625d    Inode: 2851019     Links: 1
Access: (0400/-r--------)  Uid: ( 1000/hstoerne)   Gid: ( 1000/hstoerne)
Access: 2013-02-14 14:06:56.000000000 +0100
Modify: 2013-02-14 14:07:10.000000000 +0100
Change: 2013-02-14 14:07:26.000000000 +0100

Note that "Change:" is different from "Modify:" - it shows when the chmod
happened.

Perhaps that could give you a clue ?
