Neither of those tracebacks look like they come out of the 'faster' session machinery itself; it uses an 'OOBTree' by default for storing the slices, not an 'IOBtree'. The primary consumer of 'IOBTree' is probably the catalog, where it is used to map RID -> values in the 'unindex' of 'FieldIndex', etc. The original sessioning machinery uses 'IOBTree', too: are you sure you are using the faster machnery?
