Hi,
 
Has anyone experienced a problem that causes some users to be blocked for around 15mins and then be able to access again.
 
It sounds like a port is being allocated which is then clashing with something else, this keeps the persistence and once its gone for a certain time allocates a new port which is okay.
 
This would explain why it happens intermittently to various users around the world, but none at the same time.
 
I hope someone can assist with this, oh, and the firewall is off so its not that.
 
The traffic seems to be doing
 
 
[ user ]
V
V
-------------------------------------- block is here, no tcpdump info shown for the failing user
[ LVS 1 ] [ LVS 2 ]
V

[ Real Server]
 
When it works you see the ip address on the LVS machines tcpdump, if its not then it doesn't show up at all.
 
Thank you in advance,
 
Glyn Humphreys.
