Multi thread synchronization troubleshooting sync issues

I would recommend to add the logging to below classes from HAC of QA .

Doing this would help us trouble shoot the sync issue since we log more information while doing the process 

 

Changing level below to ALL(if not available add them platform->logging configure by adding the below )

de.hybris.platform.jalo.Item

de.hybris.platform.catalog.jalo.synchronization.LegacySynchronizationPersistenceAdapter

de.hybris.platform.catalog.jalo.synchronization.CatalogVersionSyncMaster

de.hybris.platform.catalog.jalo.copy.ItemCopyContext

de.hybris.platform.catalog.jalo.SyncItemCopyContext
