We are getting the below exception continuously more than 9 hours in logs as part of this functionality.
Functionality :
Copying all pages from one country(UnitedStates) to another country(England) and adjusting references for all the pages using referencesearch API. We are passing single same resourceresolver to all method in this functionality to commit after write/modify operation. Using sling jobs in this functionality to make job execution as ordered.
Observations:
Initially error is thrown at /content/test/brand1/testpage/home/jcr:content/par/richtext/item1 for 2 hours. Later I deleted home page to stop this error and same error is thrown at /content/test/brand1/testpage for more than 6 hours.
Question :
I know this error might be multiple update on same node by different thread. In our code, this exception was catched in respective method and just log it for reference to proceed further(not throwing custom exception). But I don't know why this exception is repeated appearing on logs.
Is there any way to stop this exception without restarting the instance or sling jobs bundle ? I tried to stop sling job via SlingEvent console and getting different error there(
