Package Management oddity

[SunnysideUK]

Several times now I have been presented with an installed package list with a red ! - Package not in repository.
After an update check all list OK again. There does not seem to be any functional problems I've noticed, just this oddity.
Any ideas what's its cause and remedy?
Note. I have already ran a fixdisk.

and after update check...

Post the output of ls -l /mod/var/opkg/ from the command prompt next time it isn't working.

humax4# ls -l /mod/var/opkg/
-rw-r--r-- 1 root root 0 Nov 6 05:43 base
drwxr-xr-x 2 root root 12288 Oct 28 14:01 info
-rw-r--r-- 1 root root 17715 Oct 28 14:01 status
drwxrwxrwx 15 root root 4096 Nov 6 05:48 tmp

So something is trashing your /mod/var/opkg/base file (0 bytes), which is the list of packages, which is why the WebIf gets upset.
Running opkg update (or Check for updates from the WebIf) and checking the file size again should show it to be about 69213.
Finding out what the root cause is is not easy unless you can pin it to anything you're doing which may give a clue.
Do I presume 05:43 is when it powers on in the morning?

Post recent update check:

humax4# ls -l /mod/var/opkg/
-rw-r--r-- 1 root root 70043 Nov 6 19:32 base
drwxr-xr-x 2 root root 12288 Oct 28 14:01 info
-rw-r--r-- 1 root root 17715 Oct 28 14:01 status
drwxrwxrwx 15 root root 4096 Nov 6 19:32 tmp

The unit was powered off over night, Not unusual if there is not schedule recording due anytime soon.
Its on a UPS and I shut it that down, Humax in full standby.
I woke up the unit to do some ad-removal work w/o problem.
Then mindful of the package problem, I checked and noticed the problem was back (it was OK yesterday).
