#### Possible Causes

The ECS memory is insufficient.

#### Solution

- Method 1 (recommended)

  Modify the ECS specifications to increase the vCPUs and memory size. For instructions about how to modify ECS specifications, see General Operations for Modifying Specifications.

- Method 2

  Enable virtual memory on the ECS to obtain its idle memory.
