Do you have anything in your logs? /var/log/kudu/kudu-tserver.WARNING for
example? or .INFO? The last few lines should be informative as to what is
causing it to crash.

It should be located in the same directory as the logs, by default. I think
it can be configured, but I'd check there first.

That's very surprising. A crash of a server should never lose data. How are
you determining that data is lost? We do extensive testing with crashing
servers and have not seen data loss in probably a year or so.
