TdS blockexplorer stuck due to redis configuration

[mvines]

The TdS api server stopped at block 78784, transaction count 2049592. Looking at the api server log I see this re-occurring error:

(node:22213) UnhandledPromiseRejectionWarning: ReplyError: MISCONF Redis is configured to save RDB snapshots, but it is currently not able to persist on disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.

Need insight into host HW specs/disk space to debug...

Suggestion: add disk space 2-3x the RAM size at the persist file location specified in /etc/redis/redis.conf if it's not there already?

this hasn't popped up lately; if it does, there is info at https://redis.io/topics/lru-cache
