Dear experts,
Does anyone knows about known issues with SAP Kernel 721 ext PL 412?
I have applied to my CRM system and I having some dumps (SYSTEM_CORE_DUMPED), I don't know if this kernel has any bug or if the problem is because the system has other problem (I left the logs for further analysis).
I have been looking for Known Issues with this kernel (It is the last one) and I don’t find any relevant information regarding to this dumps, the only note I have found is 1728283 - SAP Kernel 721: General Information and in the last part the known issues make reference to other issues.
Please refer to note 2084437 for other known issues with SAP kernel 721 PL 401.
I appreciate any comments that help me to troubleshoot the issue.
Dear all,
From logfiles the findings were:
In the work process log stack corrupted information this error are due to mainly kernel bugs. The recommendation was to apply the DW_416 kernel package as it consists of many fixes.
It should be noted that this problem only happens in my distributed system since the kernel was applied before in two centralized systems and the DUMP never appeared.
In this context I will apply again the DW_416 Kernel Package in order to fix the inconsistencies. I will let you know what happen next. Thanks for your suggestions.

Hello Daniel,
the call stack in the traces is corrupt, could you please try to extract the call stack as described in the note
625271 - AIX call stack denoted as corrupted in trace files

Alwina

Hi Daniel ,
Check whether you have the recommended C/C++ Runtime
1780629 - AIX: Minimal OS Requirements for SAP Kernel
Thanks ,

Not sure that this issue is related to any kernel bug. At first the cause of CX_SY_DYN_TABLE_ILL_COMP_VAL exception is "a column of the table otab contains a prohibited value". According to explanation: "If a column of otab, has invalid content (NAME contains the name of a component that does not exist or an incorrect offset/length specification, DESCENDING and ASTEXT do not contain "X" or the initial value), this leads to a treatable exception of the class CX_SY_DYN_TABLE_ILL_COMP_VAL". In your case otab is lt_sortbytab. An exception has occurred in program ZRVEUR101_CALC_SEGMENTO. Try to debug (with help of the program owner) to investigate the root cause of this error.
In addition can you attach output of errpt command at time when system dump has been occurred?

Hi Daniel,
You should not be using that kernel sub-version without specific reason (Oss note or SAP support recommendation).
Only apply main SP Stack kernel patch (that is SP 401 for 721 EX6 Aix => SAPEXE_401-10011318.SAR)
Check on swdc, the 412 kernel has gone & is repalced by 415 (dw_415-10011318.sar)
Check page 8 of this document => Deployment Strategies for the Kernel of the SAP Application Server ABAP
The trace file is note the one of the process that did undergo the dump.
87 WP, it's starting to be a big instance...
If not already done, check instance profile & memory def. (1137734 - Assignment of memory areas, shared memories, and pools)
sappfpar check pf=/sapmnt/DIM/profile/DIM_DVEBMGS00_machine02
