[jira] [Created] (ARTEMIS-3271) Avoid Multi Thread measurement on Critical Analyzer

Clebert Suconic created ARTEMIS-3271:
----------------------------------------

             Summary: Avoid Multi Thread measurement on Critical Analyzer
                 Key: ARTEMIS-3271
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-3271
             Project: ActiveMQ Artemis
          Issue Type: Bug
    Affects Versions: 2.17.0
            Reporter: Clebert Suconic
             Fix For: 2.18.0


The Critical Analyzer could be called from multiple Threads.

 

As a result, I am afraid there could be a situation that left time was updated at a wrong pace.. leaving to inconsistencies.

 

 

I'm improving it to only consider a single thread from all the calls. Any calls from multi-threading should be ignored... All we need is to capture one thread hanging and detect a dead lock.
