The info in the SLDataGateway dump should be enough to link the leak to a certain element or request that is being done. Occasionally it can be useful to look into the memory of the calling process. The most important ones are:

• SLElement (Handles most of the data generation that ends up in DBGateway)
• SLNet (handles most of the client requests)
• SLASPConnection (some reporter calls go through this)

Do keep in mind, with a memory leak it is very important to take multiple dumps over the course of the memory increase.
