Description

Look at how errors during read are logged, current implementation could flood logs with stack traces on failures.

proposed

• errors in prefetch only logged at info with error text but not stack
• full stack logged at debug

but: we do want the most recent failure to be raised on the next read() on the stream when there is no data in the cache.
