Comment 2 Martin Entlicher 2012-04-10 09:59:27 UTC 
The heap dump is incomplete, but we can see five large Strings there, having 33.5 MB each and the reference chain.
We need to improve handling of large Strings, not to load them all into the memory. Something was already done in that area, but apparently, it's not enough.
