Memory leak with version 1.2.11 #302

Open hlange opened 5 years ago

hlange commented 5 years ago

I am currently developing a client that sends and receives data using UAMQP, but the memory is growing.

Since I work on a Windows system, I studied the program with DrMemory, which tells me the following:
