I notice a strange behavior of my CSM-S when I am trying to use the active cookie sticky method.
I have a server farm with 2 servers. When I tried to open a session to the VIP ip address, everything works fine until I try to open one of the links in the java menu for the second time. In the sniffer trace I can see that after the HTTP request is being sent the load-balancer answer with RST packet.
Even if I take out of service one of the real server in this farm I have the same problem.
Does anybody know why I might receive this RST packet, especially if I am doing test with one real server?
When I change the sticky method to e.g. source IP everything works fine.
Thank you in advance for any help.
ok, from the trace it seems like the request is so long the CSM can't find the cookie and reset the connection.
Do the following command to verify this :
sho mod csm 3 tech proc 4 | i arse
LB Rjct: L7 max parse len 0
LB Rjct: L7 parser 0
See if any of this counter is increasing.
If yes, under the vserver configure
This should fix the problem.
A trace is always helpuf :-)
