Hello

We have been using Geronimo 2.2-SNAPSHOT in production for a good month now, and I thought I'd share some experiences with the community, and maybe get some help. We are an online backup service, check out jottabackup.com if you're interested.

Generally our experience has been very positive. We're using the GBean framework for custom server components, the DB connection pools against MySQL databases, stateless service EJBs and various MDB, and of course the web tier (Jetty). Everything is running smoothly and we're very much looking forward to 2.2 being released so we can "release" our own software.

The issues we're having are related to WADI clustering with Jetty. First we can't use Jetty7 because of GERONIMO-4846, so we're using Jetty6 which works fine. The more serious issue is that we often can not update our servers without downtime. This is what happens:

We have 2 application servers (AS-000 and AS-001) running dynamic WADI HTTP session replication between them. When updating we first stop one, AS-000 in this case. That works fine and the active sessions are migrated to AS-001:

, however AS-001 then just hangs, and we have to kill the process to get it stopped. After this we can start AS-000, update AS-001 and it always seems to have no problem joining the cluster thereafter. The strange thing is that this problem does not always occur, sometimes everything goes fine. I can't find a consistent pattern but I've tried stopping AS-001 before AS-000, and I'm sure no serializable object in the session has changed between the updated and running instance.


My gut feeling is that this is either a concurrency-related bug in WADI or a network-timeout related problem. During normal operation I'm sometimes seeing messages like this in the log files:

Does anyone have some insight into what might be causing this, or where the timeouts can be increased if there are any?

I'm thinking that a static WADI configuration can be more stable than the dynamic setup we have not which relies upon multicasting. Does anyone have experience with similar setups?

Thanks!
