Hello, it is not a test application it is our online shop in a load test using a professional load tool (PureLoad). Objects are loaded from the database and stored in the cache based on queries in http requests. I should mention that the long GCs occur mostly during the cache warmup phase and that memory is quite stable after that. I should also mention that we load the application quite heavily, the average GET frequency on a single JBossCache is around 3000 per second.
We are using the fc-fast configuration (as defined in JGroups 2.2.7) which have worked well in production. Anyway, I don't expect you to be able to diagnose any possible cause. There could be many reasons for this behavior where some of which may be related to the application server or JDK. Since we are looking into upgrading/changing J2EE platform in the near future I think we are going to revisit the JBossCache/JGroups upgrade at that time. (BTW thank you for the dinner conversation we had in Stockholm in March. It was very interesting to hear about your plans for JGroups in the future.)
