conflicting packet

Hello, i receive this message on radius.log Error: Received conflicting packet from client GGSN1 port 61137 - ID: 96 due to unfinished request in module <queue>. Giving up on old request. i need to print the Calling-Station-Id and the Acct-Status-Type related to this packet I was able to do this when the packet is on module <detail> by modification done on the process.c file but when packet is on <queue> module it doen't print the Calling-Station-Id, could you give me an idea how to get Calling-Station-Id when packet is on <queue> module? Thanks Bassem
