resources problem - by: ulix86

Hi, I have a problem with computer resources when I run my vb6 exe (QuickOpc 2019.2).
My program starts the OpenConnection function every 15 seconds for testing the status of the machine,
but after few hours the process keeps a lot of resources in Windows TaskManager like 1 GB or more.
I already tried to close every connection and set object to "nothing" but the problem remains.
It's like something does not clear the memory or the connection still open.

Could you help me?

Thank you
