Levon Saldamli:

I have an application running with sqlalchemy which periodically imports some archives and creates database model objects, where objects of type BindParameter keeps increasing each time by some numbers. But I can't find any references to these objects that also increase. I'm using pdb and objgraph to find references, and as far as I can see using those tools, only BinaryExpression objects refer to BindParameter objects, but there is also a cyclic reference from Comparator objects (also not increasing in number). Is this a memory leak?

See attached graph of the references. At this moment number of objects in memory are: Comparator=3, BinaryExpression=11, BindParameter=569
