Error description
Dump Title: COMP=JES2,COMPID=SC1BH,ISSUER=HASCLINK-RECOVERY, SSI=WTO MESSAGES,CODE=U0920 CONSOLE flooded with messages: T KO2O0952E GETMEM > LIMIT: 1D0BC9C4 NONCONT OSYXDSYS $C2WORK BASE R14=00000000 SYSTRACE shows a recursive ABEND0C4-11 in KOBBASEM+86A (at UA50713 level) on a 954E9000 instruction (CLI), with R9 bad. R9 did not point to the current output buffer as KOBBASEM expected resulting in the program check. Following this ABEND0C4, KOBINT1M (BASE ESPIE) gets control to handle the error and passes control to KO2ORCVB (INTERCEPT PROGRAM CHECK ROUTINE). KO2ORCVB considers doing a retry, but detects that z/OS DB2 in unavailable and instead passes control to the caller's IFNODB2 exit. The caller was KO2OSYXB and the exit is KO2OSYXB+302 (at PK79664 level). KO2OSYXB calls KO2OMEMB to get a work area, but because the base R7 has changed, calls KO2OMEMB with a bad length -- 1D0BC9C4. This length is unpredictable and depends on storage contents. KO2OMEMB detects this bad length and issues the KO2O0952E message and exits to KOBBASEM+6DC, the point in code to handle: COMMAND ENTRY PROCESSING - END OF COMMAND. Eventually KOBBASEM will try to update the current buffer for the DSYS comand and program check, leading to another iteration of the loop. Since Omegamon has gone through this more than 600,000 in this failure, JES2 detects this and excessive storage use and ABENDs Omegamon.
