How to Fix Error: Memory allocation failed

Topic: Linux Ubuntu Boot Errors | Status: Updated

What is this error?

The "Error: Memory allocation failed" message indicates that the system has encountered an issue allocating memory during the boot process. This error often occurs due to insufficient system memory, misconfigured swap space, or hardware problems affecting memory availability.

How to Fix It

  1. Check Physical Memory: Ensure that all RAM sticks are properly seated in their slots. Power down the system, open the case, and reseat the RAM if necessary.
  2. Run Memory Tests: Use the built-in memory test utility in Ubuntu. Access it by rebooting the system and selecting "Memory Test" from the GRUB menu to check for faulty RAM.
  3. Inspect Swap Configuration: Verify if the swap space is properly configured. Check the swap space with the command swapon --show to see if it is active and verify its size.
  4. Create or Increase Swap Space: If there is no swap space or the existing swap is insufficient, create or increase it. Use the following commands to create a swap file, for example:
    5. sudo fallocate -l 2G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile
  5. Update System: Ensure that your Linux kernel and system packages are up to date. Run sudo apt update && sudo apt upgrade from the terminal to apply any pending updates.
  6. Check for Hardware Issues: If problems persist, consider testing your hardware for faults, particularly the RAM and motherboard, as these defects may lead to memory allocation failures.
  7. Consult System Logs: Check system logs for additional clues regarding the error. Use journalctl -xb to look for warnings or errors related to memory allocation during boot.
