Hi,

looks like a hardware issue.

You need to RMA the WLC or else opened a TAC case.

Looks like broken compact flash card in the WLC. If you still have warranty RMA it, if not, you might be able to buy a used one for little money (as it's already very old). Alternatively, get a newer model, like the 3504 (which is also already outdated, but could be mostly compatible with the configuration backup....).

That sounds like some part of the hardware is broken. I would look for a replacement of the whole WLC.

I don’t think you want to try to fix it yourself. You might as well find another 2504 or look for a 3504.

DDR clock is typically the RAM. Based on the error I more suspect a file system corruption, which is much more common.
