It's possible that what you were seeing was an indirect effect of the now-known bug: if the xpath leak were to occur repeatedly on a large scale in a long-lived session, I think it's possible that memory allocation behavior might suffer due to fragmentation effects. I feel that that's a pretty hand-wavy explanation though. Probably the right thing for you to do now is just to install the known fix, and keep an eye on your server for awhile to see if you still see any indication of the long-term leak behavior. regards, tom lane
