> I am using Kafka consumer to fetch objects from Kafka topic and then persist them in DB.
> When I ran, eclipse MAT for memory leaks, its giving following :
> 53 instances of *"java.util.zip.ZipFile$Source"*, loaded by *"<system class loader>"* occupy *22,33,048 (31.01%)* bytes.
> Also, my observation is that GC is not collecting objects.
> Please let me know if more information is required.
