OPC UA memory issue

Dear team,

I am developing the opc ua server with the 1.6.3 stack. And I found that the OPC UA server didn't release the occupied memory when the server is closed. Also, this problem only occurs on the Linux RT OS.
And in fact, I only created some folder, items in the server. Why this phenomenon occurs? How can I resolve this problem?

Hello zheng,

we do tons of tests monitoring the memory and resource consumption for every release. I assume the issue is related to the way you use the SDK or to the custom code. Can you figure out what exactly leaks? Do you have any tools helping you for that like Clang MemorySanitizer?
Can you provide any example (based on SDK example ServerHelloWorld) that shows this issue?
