[users@httpd] Apache,php to mysql problem

[Vasiliy Boulytchev <vasiliy@xxxxxxxxxxxxxxxx>]

Ladies and Gents,

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

	Diagram:
			

       		    Internet			
			X			
			XXXXX mysql server			
			X
		LVS Load Balancer
		    x      x
		   X        X
		  X          X
		 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!
