it crashed today morning, so 2.6.13mm is not much better than 2.6.14.

My fs is heavly used (but not overloaded) by many apache process or ftp 
process or postfix process.

I have free hosting server and i think i will have to close this thing 
becouse for over a month its often downtime everyday. Could you please 
tell us if there is any idea of how to fix it? i would move to another 
more stable fs but its too much data...
