Hi Mani, The fact that the issue is occurring with Resin 4 also leads me to think it's not an issue related to Resin at all. It could be something related to Apache. It would help you can take that out of the equation but accessing Resin directly. The only other possibility that occurs to me right now is database lock contention for the same rows, since you say it's occurring when the same users connect.
