Memory leak in QuickOPC nuget was created by janko.mihelic@adnet.hr
Hello,

We found out that by subscribing to OPC UA events and value changes in a way shown by example posted on github page github.com/lermix/OpcLabBug/tree/master/OpcLabsBug process memory piles up.

We are using OpcLabs.QuickOpc nuget version 5.63.246 and are connecting to PLC Siemens CPU 1512SP-1 PN. We are receiving a value change approximately every 14 ms and an event every 10 ms. Can you analyze the way we are subscribing and tell us if there is something we are doing wrong or is it just too much events and value changes. The memory grows approximately 1 Mb per minute.
