This error explicitly means “we can’t find the event in cache, but the job exists in the queue.”

This can happen in a couple scenarios:

These jobs were taking longer than 1 hour to get pulled from the queue and they got TTLd away, which is expected behavior.  
The cache was purged and these keys are literally just missing.  
Some other misconfiguration where maybe the blobs are being written into one cache, then trying to be read from a different one.  
Other than that, I’m unsure what could be wrong. Hopefully this points you in the right direction.

Thanks for the info, it seems like the main issue was our server was being overwhelmed by reports causing it to fall back, and many of them started to timeout, I added a quata, and it seems like thing are back on track

I was wondering is there a document/article/diagram that shows the lifetime of a report as far as different system components are concerned? I’ve tried looking for one, but I wasn’t able to find it (besides https://docs.sentry.io/server/queue/ 225 which is pretty light on details)

Here is what I’ve gathered and guessed,:

Report is sent by client to dashboard node  
Dashboard node stores the raw event in the cache you mentioned. (Is this cache the same as what is referred to as queue/broker)?  
The report is picked up from the cache by the worker node and updated in Postgres. (What I’m confused about is why the worker can pick up the cache key but not the item? are they stored in different systems and only one of those systems has TTL?).

For what it’s worth, we ran into the same issue and ended up cleaning the backlog with:

sentry queues purge events.preprocess_event

From one of the worker nodes.

Once that was done, all backed up events were lost (as expected) but processing resumed as normal and new events are treated properly.
