Application crash in OPC code - by: spicerno

Hello,

after upgrading the quick opc version to Quick OPC 2022.1 (5.63.121) we're experiencing a crash when interacting with an OPC DA server.
we were successfully using a really old version of quickopc from 2018, and we had to revert back to it to keep the system running.

Our application is a windows service implemented in .net 4.7.x , running on windows 2016.

An unhandled exception is fired on system threadpool and leads to application crash.

Here is the stack trace:



Is it a known problem ? Is there a way to mitigate it ?

Thanks in advance
Stefano
