|0004474||[Resin]||minor||always||04-04-11 10:23||04-05-11 12:43|
|ETA||none||Fixed in Version||4.0.17||Product Version||4.0.16|
|Summary||0004474: multiple webapp instances (not versioned) in 4.0.16|
(rep by Mattias Jiderhamn)
While evaluating Resin 4.0.16 we are seeing something that makes me really concerned. It appears as if after a redeploy there can be two instances of our main app running.
I was made aware of this by noticing that timed servlets (<run-at ... />) were having concurrency issues and logging the same event twice within the same second.
This made me add some extra logging in a <load-on-startup/> servlet, and I can actually see that at some reploys, the same web app is initialized twice - in different, concurrent threads and different classloaders.
For example one instance may be initialized by Thread[http://*:8080-776,5,main] [^] and at the same time (give or take a few seconds) another one by Thread[resin-366,5,main].
I cannot deliberately recreate it by simply redeploying (which makes it less likely to be a configuration issue). But it happens about daily on our test server; possibly issuing requests on a session in the app while redeploying is a factor.
We are not using versioning.
dependency-check-interval is set to 20 seconds.
The "extra" app does not appear in the admin console.
How can we figure out what is going on here???
