Sorry, I did not see the responses here because I found out myself. I
definitely seems like a hard commit it performed when shutting down
gracefully. The info I got from production was wrong.
It is not necessarily obvious that you will loose data on "kill -9". The
tlog ought to save you, but it probably not 100% bulletproof.
We are not using the bin/solr script (yet)

From my research it looks like it will do a hard commit if cleanly shut
down. However if you "kill -9" it you'll loose data (obviously). Perhaps
production isn't cleanly shutting down solr?

I do not know whether a graceful shutdown does a hard commit or not.
I do know that all versions of Solr that utilize the bin/solr script are
configured by default to forcibly kill Solr only five seconds after the
graceful shutdown is requested. Five seconds is usually not enough time
for production installs, so it needs to be increased. The only way to
do this currently is to edit the bin/solr script directly.
Thanks,
