I think error code 137 is not enough memory.

Do you have a swap file set up? You can check by running `free` on the command line.

Alternatively, you could upgrade and add more RAM?

One I haven’t tried yet but have read a few times on here is adding `vm.overcommit_memory = 1` to /etc/sysctl.conf

**Edit:** This is from a different-but-similar topic, and has the text from the log in:

> 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.
