Full Synchronization Error: Java heap space

Scenarios

During full synchronization, an error is reported, and the log information is as follows: service DATAMOVE failed, cause by: Java heap space.

Possible Causes

A large number of fields exist in the service. As a result, the memory usage of the synchronization task exceeds the threshold.

Solution

Check whether the task is normal.
- If the task is normal, this error is recorded in the log and no further action is required.
- If the task is abnormal, go to 2.
In the upper right corner of the console, choose Service Tickets > Create Service Ticket and contact customer service.
