When we made the following change…

###################################### 
### Force Indexing to Background ####

index.tracking.disableInTransactionIndexing=true 
lucene.maxAtomicTransformationTime=0 ‍‍‍‍‍

the problem with the memory leak went away, but then Lucene indexing stopped functioning.

This makes us believe the Lucene index is the real reason behind this memory leak. I found some forums suggesting there are problems in the earlier versions of alfresco 3 but 3.4d was supposed to have them fixed.

But isn't that strange? Because normally a Lucene memory leak would show a huge quantity of org.apache.lucene.* in the Heap. But as you see from my heap analysis from MAT, that is not the case! HELP!!

Did you manage to find a solution to this problem?
We are having a similar issue and can not figure out how to resolve it. Out of desperation I am thinking about just upgrading to the latest version but that is likely to cause more problems than it solves so if you did find a fix I would really appreciate you posting it.
Thanks
