You seem to be hitting effects of CSCin98933. This bug is fixed in
12.4(10), but you might have run into it using an earlier release and
caused the nvram corruption. The bug's release note says:

---snip--
[...]
When you have upgraded the Cisco IOS software image to one that
integrates 
the fix for caveat CSCin98933, take the following steps:

1) Create a backup copy of all the required files in NVRAM.

2) Erase the entire NVRAM by entering the "erase /all 
nvram:" command, thereby ensuring that there are no stale pointers 
in NVRAM and that the NVRAM device is filled with 0x0 or 0xFF patterns.

Note: The erase nvram: or write erase command erases only the partial 
contents of NVRAM.

3) Next, restore the files that were previously in NVRAM back to NVRAM
via 
the copy and write memory commands.

can you please try this?
