Hi Peter,
I used Eclipse MAT (a great tools IMHO!) and also JProfiler. This is the difference between the memory after 50min and 63min (the peak is around 60min).
I trace the GC also and I notice a strange behavior of Survivor Space when the GC begin its intensive activity (after 1h). It seems that it exceeded the maximum:
Exploring the memory dump, the Maps and ZipEntries seem to be related to MBean map and deploy/vfs structures. Their shortest path to GC root involve http- threads.
This could be related to connection pools or aliveness of connections?
Thank you for any tips about this
