I am having a issue where the Redis in memory database is like 1.9GB, what modules or what features use the Redis database engine? Every about 5~8 minutes it dumps its database to disk basically stopping asterisk processing for 20 seconds or so because of the IO load while writing a 1.9GB file, taking the system load from 0.4 to over 5.0 instantly. Any suggestion?
Good question - that’s what I would like to know, too.
Well, a little more info I discovered. I downloaded redis tools and ran a memory scan of the keys and came up with this -
In the tune of 99,000+ lines, Now why is the question? At least I know the issue is Zulu.
Ok, for anyone that may run across this, there is a fix. And they are suppose to build a fix in future versions, if you have a excessive database file run this command to trim it -
redis-cli KEYS "zulu_*" | xargs redis-cli DEL
That will fix the issue.
