Hello @cuiw,

these are task which are created during runtime (more precise, during the profiling) by libraries, mapp components or the OPC UA server (as an example).  
Usually it is enough to increase the size of “Buffer for created tasks” and “Buffer for created user tasks” in the profiler settings as described [here](https://help.br-automation.com/#/de/4/diagnostics_support%2Fdiagnosis%2Fprofile%2Fanalyze%2Fdetails%2Fdiagnosis_profile_analyze_details_buffer.html).

You can find additional information on the profiler in this [article](https://community.br-automation.com/t/how-to-create-a-long-profiler-with-enough-data-for-analysis/493).

Best regards  
Fabian
