Rading this thread about xfs vs ext3, and how ext3 is safer...

I just got ("just" as in "today") an error on one of my ext3 file  
systems.  Reason?  Userspace application allocated a larger chunk of  
memory, kernel generated OOM (while there was about 1 gig of swap  
still free), and an completely unrelated ext3 file system (app in  
question wasn't doing anything on it) got an error, automatically was  
remoutned read-only, and marked as in need of fsck.

I've unmounted it, run fsck on it (it found some errors and fixed  
them), and now each time I try to mount that file system kernel  
reports the file system is marked as having error from previous mount  
and that it is in need of fsck.

<flame mode="on">
Now, I wouldn't call this kind of thing "stable" operating system or  
"stable" file system.  If application asks for too much memory it  
should get killed (btw, system had 1 gig of RAM and application asked  
for like 600 meg, plus there was plenty of swap space free too -- so I  
wouldn't call this a case of app asking too much).  You definetely  
don't end up with corrupted file system.
