Siebel Native Load Balancing

Hi,

Customer has enabled Siebel Native Load Balancing and are experiencing uneven distribution of connections for their EAI OM. eApps.cfg has the entry as below for anonymous and regular type connections- both types of connection go to same EAI OM as below.

[/eai_enu]

ConnectString = siebel.TCPIP.None.None://VirtualServer2/SBLENT/EAIObjMgr_enu

EnableExtServiceOnly  = TRUE

WebPublicRootDir = \sba81\sweapp\public\enu

SiebEntSecToken = xxxxxxxx

[/eai_anon_enu]

ConnectString = siebel.TCPIP.None.None://VirtualServer2/SBLENT/EAIObjMgr_enu

EnableExtServiceOnly  = TRUE

UseAnonPool  = TRUE

AnonUserPool  = 60

WebPublicRootDir = \sba81\sweapp\public\enu

SiebEntSecToken = xxxxxxxx

There are 4 EAI Severs - once one of them hits the max limit, connections start timing out and are not routed to next one. Once it is shut down, new incoming connections get routed to second server and once that gets maxed out and is shut down, connections are routed to third server and so on. Although configuration in lbconfig.txt and eApps.cfg seems fine - wonder if there is any parameter that might be missing or set incorrectly. What else could cause this behavior if config is fine? Would appreciate any feedback.
