Udo,
These kind of dump occur when we have a memory mismatch and a 0 is returned from the kernel and lost the connection due less space and for which the sap will dump.
OR
This may happen even when the program is happening to run through the authority_check.
If you can go through 1945439 you can get more information and looks like this note will be applicable to your up gradation.
If you can clear some memory and try again it will help. This dump is a forced dump.
