Possible failure to start Alfresco node in a clustered environment #337

Open kpiot123 opened 2 years ago

kpiot123 commented 2 years ago

In a clustered environment it is possible for some Alfresco nodes to fail to start due to an exception related to dynamic-extensions. It happens when the osgi container module component is executed more than once while starting Alfresco. The reason why it is started multiple times is unknown.

This issue only seems to occur when all the cluster nodes are started at the same time. If the cluster nodes are start one by one with a short pause in between the issue does not occur.

Expected Behavior

The osgi container module component is only executed once on start-up of Alfresco.

Current Behavior

Sometimes an exception occurs on start-up of Alfresco:

At that point the osgi container module component is about to be executed a second time.

Possible Solution

There is no solution yet. The only work-around is to start the cluster nodes one by one with a short pause in between.

Steps to Reproduce (for bugs)

The issue can't consistently be reproduced. It only happens sporadically

I don't believe this is a DE issue, rather a bug in Alfresco?
