Subject couchdb restarting every 10 minutes.

hi there,

We have a couchdb instance hosted on AWS's x.large instance, and it's 
restart about every 10 minutes. Here is couch.log looks like when it 
crashed.

Any hints on what the problem could be?  We are hosting about 19000+  
database of this machine with pretty high file descriptor limits.

Thanks in advance,
Herman
