How to avoid huge system resource consume , when SSO can login in many time

Hi all.

We implement the EP-SSO LogonTicket -- SAP R/3.

But user can use EP-SSO login in R/3 for many sessions, there is no session control.

If in this situation, how R/3 system can avoid the huge system resource consume ? Because users can connect to R3 for many sessions.

Its urgent question because without give customer a good reply, they cannot put the project online.

Is there some experts ?
