  I crested a new blazor app. Used abp suite to add some entities.

  Deployed on iis. Worked well for one month. Then all over sudden, 6 hours every day in the morning. The Application stops responding.

  IIS cpu utilisation is at 100 %.

  Then later on everything goes back to normal

  Seems there is a performance issue in .net 5.1. Have found out this error happens when I have 20 + api calls concurrently.

  How can I add api rate limiting in abpb?

  How can I improve performance with many api calls?

  one thread is doing SpinWait wasting CPU cycles.

  Can you verify the method DoWorkAsync? The condition if (1== 0) , probably was introduced for testing purposes and remained in the code.

  This doesn't seem to be code built into our module?

  Can you share more information?

  A task was canceled.

  This exception is usually the caller canceling the call due to timeout or other reasons.

  Can you share code or a simple project that reproduces the problem?
