[GitHub] [pulsar] lhotari opened a new pull request, #15737: [Broker] Prevent the trigger running concurrently in the memory limit controller

[GitBox <gi...@apache.org>]

lhotari opened a new pull request, #15737:
URL: https://github.com/apache/pulsar/pull/15737

   ### Motivation
   
   - under load, it's possible that the trigger immediately releases memory and causes the current
     usage to go under the limit while the trigger is executing. If a memory reservation call that exceed the limit occurs while the trigger is still executing, it would cause the trigger to be run even though the previous one is still executing. This scenario should be prevented.
   
   - the trigger was introduced in #15216
   
   ### Modifications
   
   - prevent the trigger being run concurrently
