TCP RST issues

Phusion Passenger version 3.0.18
nginx version: nginx/1.2.4
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]
rails (3.0.20)

MULTIPLE RESETS

I usually see 20-25 database connections from my ruby/passenger/nginx
server to the database server. I am seeing lots of TCP Resets and
dropped
mysql connections.
I run the DB on port 3312…and using tcpdump I can see the db sends a
[S.] SYN-ACK but the rails server responds with a [R] RESET immediately.
tcptrack on port 3312 shows 20-25 established connections then all of a
sudden it jumps to 300-600 connections but the majority are RESET (s)
Any
idea why rails would besending a RESET off so many DB connections (more
then are even established)

Any help or adive would be greatly appreciated
