Sometimes Redis will throw out error:

    MISCONF Redis is configured to save RDB snapshots, but is currently not able to persist on disk. Commands that may modify the data set are disabled. Please check Redis logs for details about the error.

Override Error in Redis Configuration

Using redis-cli, you can stop it trying to save the snapshot:

config set stop-writes-on-bgsave-error no

This is a quick workaround, but if you care about the data you are using it for, you should check to make sure why BGSAVE failed in first place.

This gives a temporary fix to the problem. However, it is a horrible way to over look this error, since what this option does is stop redis from notifying that writes have been stopped and to move on without writing the data in a snapshot. This is simply ignoring this error.

Save Redis on Low Memory

There might be errors during the bgsave process due to low memory.

This error occurs because of BGSAVE being failed. During BGSAVE,  Redis forks a child process to save the data on disk. Although exact reason for failure of BGSAVE can be checked from logs (usually at /var/log/redis/redis-server.log on linux machines) but a lot of the times BGSAVE fails because the fork can't allocate memory. Many times the fork fails to allocate memory  (although the machine has enough RAM available) because of a conflicting optimization by the OS.

As can be read from Redis FAQ:

Background saving is failing with a fork() error under Linux even if I've a lot of free RAM!

shareovercommit_memory

overcommit_memory

# echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf
# sysctl vm.overcommit_memory=1

Redis doesn't need as much memory as the OS thinks it does to write to disk, so may pre-emptively fail the fork.
