Re: Production db server getting freezed

Is the storage for this system external?  SAN to NAS I mean?  It may be the 
storage connectivity is getting lost once in a while.  

There could be other reasons like cron job that is taking all resources or a 
failing hardware.  You will have to poke around until you can find it.  It help 
if you are graphing the system's statistics with for example cacti as you can 
identify a trend, or interaction of different system's statistics.
