Description
Describe the bug
Sometimes getting:
stream error: rpc error: code = Internal desc = Internal error: `Postcard error: Found a varint that didn't terminate. Is the usize too big for this platform?`.
when querying my searcher node via jaeger-query.
This doesn't happen all the time and seems to work most of the time on subsequent attempts.
Steps to reproduce (if applicable)
- "Find traces" using jaeger-query
Expected behavior
Not getting an error
Configuration:
- Quickwit 0.6.4
- Jaeger 1.50
- Backblaze B2 for storage

Research direction
Reproduce the intermittent failure by querying a searcher node through jaeger-query with Quickwit 0.6.4, Jaeger 1.50, and Backblaze B2 storage. Investigate the Postcard decoding error and verify that Find traces completes without the stream or varint error.
