The client appears to have stopped running - by: xpycy001

Hi,support :

I have encountered the following problem, please provide some suggestions for handling it

[A] Problem description
1 The OPC UA client appears to have stopped working, the application CPU is still floating up and down (0-1%), and the memory is approximately 700MB
2 All subscription data collection stopped on January 24, 2024 at 04:14, and all other worker threads stopped


Operational troubleshooting issues
1 Before closing the application, a memory mirror document (DMP) was stored separately through a process
2. Open the DMP document in the attachment, which appears to have over 2000 tasks, most of which reside in memory for a long time. Open tasks related to opcWriteValue transactions

[C] Randomly viewed a set of tasks
About 20% IPArallelismExtension+<> Task
About 80% UaSCUaBinaryChannel+Write... Task
In addition, there are about 110 tasks for Reconnector

[D] Here is our information:
1 Windows Server20216 enterprise
2 .netcore 7.05 + OPC UA SDK 5.72.522

[E]
1 Closed a batch of problem Tags
2 Fixed subscription methods for many tags, for those that do not support conditional subscriptions
