So, I'm in the process of testing LVS as a replacement to our current 
hardware load balancer.  For now, I'm implementing this for POP/IMAP.  
I've run into a couple problems:

1) If I leave the virtual alone for a while and come back and try to 
make a connection, the connection times out.  If I keep trying, then 
eventually a connection will be made and connections will be made 
successfully from that point forward.   If no further connections are 
made to the virtual for a while (maybe 30-60 minutes?) then it happens 
again.  Does anyone have any idea what might be going on here?  The real 
servers are fine because they're the exact same servers that are being 
load balanced through the hardware load balancer.   A tcpdump from the 
virtual shows the request coming in but no return packets.

2) Which brings me to my second problem...  Where are the logs for 
LVS?   I felt that the documentation suggested that I should check 
local0, but that log is completely silent unless I myself send a syslog 
message to local0.

Lastly, I'm trying to get this all going without HA/ldirectord first so 
this is just straight LVS.  Any pointers would be great.
