loss of access to management interface, failure of spanning-tree
calculations, memory leak with SNMP polling - these are the basic
things I noted before a quick change - some of these things take a
few days to happen though so first off all seems well.

ah - yes - some of the functions chew up more memory but thats a given..at
least they have the memory for that (and not much more if you do more
than basic L3 stuff on them!) ;-)
