Unable to accept connection

Unanswered Question
Jan 4th, 2008

We have two Cisco VPN Concentrators 3005 (version 4.7.1) setup as load balancing. When we add groups, we got the email notification on the Secondary VPN Concentrator: "Unable to accept connection: no sockets available for task". We have about 18 groups on the secondary VPN Concentrator. We don't get the error message on the Primary VPN Concentrator. Do you have any suggestions? Thanks.

I have this problem too.

The error indicates that the concentrator has run out of UPD Sockets . In total there are only 64 Auth sockets available on the VPN Concentrator, which includes the group and globally assigned authentication servers. Workaround is to reduce the number of Authentication servers. Try assigning authentication servers globally instead of per group.
