I am using it in production environments, not the lenny debs as you know (it fails hard).
Atm the webs are little and use little resources. The ram usage is, as always, big. I dont know why but aolserver with openacs (4.0 and 4.5), in the production systems i have seen, always consumes a lot of ram . In systems with big amount of traffic and high usage of database you must restart it sometimes unless you want it dies alone and you must have your detection and restart scripts up to date. Atm we have not still a big thing with aol 4.5.1, only little webs
