Kelven Yang commented on CLOUDSTACK-1339:
-----------------------------------------

The issue is not caused by Spring alone, it is caused by the confliction 
between CloudStack ORM layer and Spring that both use CGLIB to generate proxy 
classes, Spring is confused and goes into panic, for every DAO objects, it 
created hundreds of proxy objects behind it.

The workaround can reduce memory consumption from 300+M to just a couple of M, 
however, the new proxy mode has an some impact to DAO, I still have to spend 
some time to get all issues resolved
