> We have a tiered storage cluster where some consumers are constantly lagging 
> behind. 
> On this cluster, we get a ton of error logs and fail fetches with the 
> following symptom: 
> {code:java}
> java.lang.IllegalStateException: This entry is marked for cleanup
>       at 
> org.apache.kafka.storage.internals.log.RemoteIndexCache$Entry.lookupOffset(RemoteIndexCache.java:569)

> {code}
> I believe this should be handled differently by either
> * Set log level to warn or info
> * reload the index entry synchronously when an offset is requested and the 
> entry is marked for cleanup. 
> We do use the default setting for 
> {{remote.log.index.file.cache.total.size.bytes}} (1GiB).
