Stop UNMS

sudo ~unms/app/unms-cli stop

Start UNMS

sudo ~unms/app/unms-cli start

Fix Redis AOF

sudo ~unms/app/unms-cli fix-redis-aof

Running the above command resolved the problem and let UNMS start working.

On the forums they seemed to recommend stopping the service and running

sudo ~unms/app/unms-cli rewrite-redis-aof

I was getting the following error when trying to run this command. Running the above command worked though.

larry@localhost:~$ sudo ~unms/app/unms-cli stop
larry@localhost:~$ sudo redis-check-aof --fix ~unms/data/redis/appendonly.aof
