Ladies and Gents,
Thank you so much for your patience, I will describe my problem in as
much detail as I can...

OH1 OH2
Problem:
Apache 2.2 on Server OH2, just stopped connecting to the mysql5
databases on mysql server. Pages just time out.
For now, things are OK, since I disabled web requests going to OH2 in
the load balancer, however, this problem needs to be addressed quickly :)
Things I have tried:
1.) I am able to connect to mysql server via command line... such as
mysql -H mysqlserver -u username -p databasename -P 3307
2.) I did tcpdumps from both ends, and packets are arriving at both
destinations. I am able to verify that packet streams look alike. I
turned on the bad server for a second in LVS, tcpdumped a sample stream,
saved it, reloaded LVS, and captured a good connection attempt.
3.) I am able to ping the mysql server from OH2, i am able to telnet to
port 3307, so I have pretty much established that the problem is not
network connectivity. I have also looked over iptables just for grins.
Nothing useful is being logged to the apache logs :(
PLEASE HELP!
THANKS!
