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

  1. 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.

  2. Submit a service ticket in the upper right corner of the management console.
