Symptom


Docker Service Overloading

Environment


  • Cortex XSOAR

Cause


  • Running too many containers on a single machine, concurrently.
  • Failure to limit container resources.
Note: The number of containers that can run at the same time, without affecting system performance, depends on a variety of factors, including CPU, memory, storage IOPs, and specific integrations.

Resolution


  1. Restart the Docker service
  2. If more than 150 containers are running at the same time, move some of the Docker workloads to other machines, either by adding engines or by adding app servers. See Docker Hardening Guide
