Hi Kristian,
You are welcome.
We are using maxdb "7.8.02 BUILD 028-121-245-008", thus the problem is similar a bug pts (1250143). Some bad indexes are accessed.
Did you perform check data regularly? If you did perform check data, please let me know the latest
time you performed it and the result.
Otherwise please perform check data when the system is not having heavy load and let me know the result. To perform the check data, you can use database studio -> check db. Or you can use dbmcli
command as per SAP note 940420.
Cheers,
James
