Cause

Issue in the product.

Issue exists for containers with Service Level Management (SLM) memory schema. Agent tries to obtain value of SWAPPAGES parameter for the container. Since SLM memory schema does not use swapped memory, agent is unable to detect value of SWAPPAGES  parameter and backup fails.

Solution

This issue has been fixed in Acronis Cyber Protect Cloud 20.08, Agent build 23138. Please update to the latest build.
