I've been running a 7200 here in my office for several months with 
no problems. I am using the 512m CF card that came with the unit. It 
has Debian installed, using ext2.

Yesterday, the Python program that had been running for weeks 
suddenly stopped running. I do not know why it stopped running, but 
when I tried to re-run it I got strange Python error messages.

I looked at some of the .py files and here is an example of what 
happened.

Original file:

def lookupNames(user,nodeID,json):
    if not access.users.findSessionUser(user):
        return serviceDenied()

Corrupted file:

def lookupNa}es(user,noeeID,json):
  `$mf not access.users.findSessionUser(user):
        return serviceDenied()

I had not changed these files in several weeks at least. Many of the 
corrupted files are files that are never written to, such as doc 
files.

I rebooted and it forced a file system check. It had so many errors 
that I quit reading them. I copied all the files back to the unit 
and it is running fine now.

It is currently not using any type of UPS or battery backup. I 
wanted to see how it handled random power outages.

Is this the result of a power loss? I can understand a corrupt file 
if it loses power while writing to it, but I didn't think it would 
corrupt random files in a random way like this.

Any idea what could have caused this?
