Symptom

l A user is running a transaction which stops and dumps with the runtime error TSV_TNEW_BLOCKS_NO_ROLL_MEMORY. l This also appears as the title of a short dump in ST22.  

Environment

l This occurs on all SAP releases.  l This occurs with all OS/DB versions.

Reproducing the Issue

l Running a number of large transactions at the same time can trigger this dump. l The dump is linked to load on the system and memory usage so can be difficult to reproduce. 

Cause

The dump TSV_TNEW_BLOCKS_NO_ROLL_MEMORY means that the roll buffer has been exhausted.                            

Resolution

1. Please check the usage of roll buffer with the following steps:            ST02 -> detail analysis menu -> history/buffer statistics -> Roll & page area  

                                                                                                                         

2. If the roll buffer has been exhausted, you can increase the size with parameter rdisp/ROLL_MAXFS, however make sure there is sufficient disk space to handle the additional size of this buffer if it writes to disk.                                                                                                                 

3. It is also recommended to increase your abap/heap_area_dia, abap/heap_area_nondia and ztta/roll_extension to at least 4GB. The abap/heap_area_total should be total of abap/heap_area_dia + abap/heap_area_nondia
