Hi Henry, Yes, these are related to the recent EhCache upgrades. Do you know when these warnings were logged? Can you reproduce it using any of the samples in Shindig? The issue is related to the code in ehcache that tries to calculate object size by walking the object graph.

This can be avoided by adding stop points with @IgnoreSizeOf annotations. Since the CacheManger or Cache <sizeOfPolicy> elements maxDepthExceededBehavior is set to "abort", the sizing operation has stopped and the reported cache size is not accurate. If performance degradation is NOT an issue at the configured limit, raise the limit value using the CacheManager or Cache <sizeOfPolicy> elements maxDepth attribute. For more information, see the Ehcache configuration documentation.
