[Ruby] Active Record looses connection to mySQL

[Daevid Vincent]

It seems that after some amount of time 
(not really sure the duration, more than an hour, less than a day), 
my service just shits the bed because it looses connection to mySQL.
mySQL mind you is perfectly happy and hasn't done anything wrong,
and all my PHP pages work fantastic. 

If I restart my ruby application, it runs perfect... until AR times out again. 
*sigh*

It's extremely frustrating. 
Anyone know anything about this?  
Is it even a known issue that is to be addressed?
Is there a work-around/patch?
