Fixing redis "ISCONF Redis is configured to save RDB snapshots"

solution_redis_misconf

check redis log /var/logs/redis/redis-server.log for write errors  

can be permissions on the redis dbump dir or memory conditions or not enough place on disk

check place on disks:

http://www.cyberciti.biz/faq/check-free-space/
```
$ df -h
```

fix memory condition:

```
echo 'vm.overcommit_memory = 1' >> /etc/sysctl.conf  # only one time! doesn't have to be every time.. if already exists won't help
sysctl vm.overcommit_memory=1
```

redis config settings to check (defaults to:) especially for permissions problem

```
dbfilename dump.rdb

dir /var/lib/redis
```

stop redis from stopping on this error (dangerous!) in /etc/redis/redis.conf

```
stop-writes-on-bgsave-error yes
```

or in redis-cli only for the running session
