Overcommit_memory Redis Error | Troubleshooting Tips

If you have come across the following message from the Redis service, you are in the right place.

WARNING: overcommit_memory is set to 0! Background save may fail under low memory condition.

To fix this issue add ‘vm.overcommit_memory = 1’ to /etc/sysctl.conf and then reboot or run the command ‘sysctl vm.overcommit_memory=1’ for this to take effect.

Today, we are going to take a look at different ways to handle this warning message:

• Adjusting the vm.overcommit_memory Setting

  First, the simplest way is to open the /etc/sysctl.conf file and add or update the following line at the end of the file:

  vm.overcommit_memory = 1

  Then, we have to reboot the machine after saving the changes made to the file.
• Listen to Redis’ Recommendations

  According to the warning message, we can resolve the issue by adding ‘vm.overcommit_memory = 1’ to /etc/sysctl.conf and then rebooting. This may help resolve the error.
• Scaling Up the Instance

  In some cases, scaling up the memory resources allocated to our Redis instance will help resolve the error. By increasing the available memory we get to boost Redis’ ability to handle data and mitigate the occurrence of low memory conditions.
• Exploring redis-overcommit-on-host

  If the above tips do not help, our experts recommend experimenting with the redis-overcommit-on-host GitHub repository. This repo offers different techniques and configurations that can be applied on the host machine to optimize memory management specifically for Redis.

Our experts recommend handling the error as soon as it appears to ensure the smooth and efficient functioning of our Redis environment.
