Deleted messages are kept in memory about rqueue HOT 5 CLOSED

@Morfild Thanks for reporting the issue.
Can you please share the exact key name that has so many bytes? This looks you've called deleteAllMessages manually either via script or from dashboard. Actually this list would be cleaned up asynchronously, but something could have missed like restart of the machine.

Also,

4882841800 bytes = 4.8GB of data, did you really had so much data in a queue? Can you also check if any of the containers had failed with Out of Memory (OOM) error?

@sonus21 Thank you for such a quick answer.
I only have that "ZCOUNT prerenderprecache${rqueue.del.prefix:del::8e7ff448-6f84-4c94-8391-afec3a19415d::prerenderprecachequeue::{prerender-precache}_medium3 -inf +inf
(integer) 6983370".
We had a bug in the system that created a large queue and I had to delete all the messages using deleteAllMessages.
Now they are stuck in redis.

You can delete this ZSET to freeup the memory. But still there would be some left over space used by message keys, they have TTL so they would go away within 14 days or so.

Yes, we deleted this ZSET. Thank you for the information

@Morfild did you observe any OOM error? As these entries are supposed to be cleanup automatically.
