SAP Note 16983 - RSTG chain destroyed

Symptom:

You receive an error message telling you that the RSTG chain is destroyed.
The developer traces contain extracts that indicate that memory has been overwritten.

Other terms

rstg_

Reason and Prerequisites

Due to an error in the application server, memory is overwritten in the
memory chains.

Solution
If you can reproduce the memory overwriter, you may be able to
determine what triggered the error by activating the memory monitoring within the ABAP Debugger.



Kernel extensions: Trace ouputs and further memory checks

As of kernel patch level 2037, the system outputs the contents of the affected memory area in the trace file of the work process for 46D kernels. You may be able to determine the cause of the error from the data content.

Check of PERM and TASK memory areas as of the following patch levels:
46D 2137
640 95
700 29

The new checks resulted in terminations (core dumps) and trace outputs:
PERM block defect
id ROLEPT addr ... len ...
or
id SHORT addr ... len ...,

This problem in the check function is solved in the following patch levels:
46D 2156
640 100
700 32
