Hi Kristian,
The check data shouldn't crash database. Also I checked the logs, there are indeed some indexes
corrupted.
However right now the top priority is to bring database back to online, please check if you are able
to bring database to online. If you are still not able to bring database online and this is your production
system, please raise an SAP very high ticket and I can taker over from my time zone. So you will have 24*7 help. If you are going to raise ticket, please upload the latest .tgz file.
Best regards,
James
