>                 URL: https://issues.apache.org/jira/browse/ACCUMULO-2288
>             Project: Accumulo
>          Issue Type: Bug
>          Components: tserver
>    Affects Versions: 1.4.4
>         Environment: 4G heap, 6G native map for tserver;
> table.compaction.minor.logs.threshold=6
>            Reporter: Mike Drob

> # Create a table
> # Add lots of splits (they'll all be on the same server)
> # Start a heavy ingest load
> # Wait for master to decide to balance
> # When master sends unload requests, tablet server dies.
> It would be good if instead of trying to flush everything at once, the tserver could
go a little bit slower, but stay up. Or at least provide better logging.
