I used cachemgr.cgi and looked at the memory utilization. My first four rows are: Pool Allocated In Use (#) (KB) (#) (KB) cbdata IdentStateData (21) 1088861 4414992 1088861 4414992 mem_node 259773 1049240 259524 1048234 cbdata ConnStateData (20) 1274359 448017 1274358 448017 Connection 2152578 403609 2152521 403598 It doesn't look like the ident connections are cleaned up properly. That explains why I have 6 GB allocated, when over 4 GB are ident structures. Mike Mitchell
