Redis memory usage counts toward your account’s total memory limit.
So if your LVE memory limit is:
  • 1GB total, and you set Redis to 1024MB, you risk:
    • Hitting the limit
    • Causing slowdowns
    • Getting processes killed (including Redis or PHP)

Safe Approach Keep Redis within 25%–50% of your LVE memory Examples:
  • LVE = 1GB → Redis: 256MB–512MB max
  • LVE = 2GB → Redis: 512MB–1GB
  • LVE = 4GB → Redis: 1GB–2GB

This applies only to servers on the new infrastructure (domains ending in .mysecurecloudhost.com or .stableserver.com).

Step 1: Access Redis in cPanel

  1. Log in to your cPanel account.
  2. Navigate to cPanel → Redis.
  3. Ensure your Redis instance is running:
    • If it is not running, click Start Redis Server.

​
Step 2: Connect to the Redis Instance


To modify Redis configuration, you’ll need to access it via the command line. Use the redis-cli tool with your instance’s port and password. For example:

Once connected, you will see a prompt similar to:

​
Step 3: Set the Maximum Memory Limit

To increase the memory allocation, run:

This example sets the limit to 1024 MB (1 GB). Adjust the value as needed for your use case.

​
Step 4: Make the Change Persistent

By default, configuration changes are temporary. To save them permanently, run:

This ensures the new memory limit persists after restarts.

​
Step 5: Verify the Configuration

To confirm the new memory allocation, run:

You should see output similar to:

The value is shown in bytes (in this case, 1024 MB = 1073741824 bytes). Restart the Redis server and flush its database.
