IN SOME RARE CIRCUMSTANCES THE PD_GET_DIAG_HIST() TABLE FUNCTION MAY HANG. | |

DB2 FOR LUW / DB2FORLUW / A50 - DB2 | |
| Problembeschreibung: | |
In some rare circumstances the PD_GET_DIAG_HIST() table function may become stuck looping without making any progress giving the outward appearance of a hang. This can leave sessions that cannot be forced from the DBMS. Operating system tools like top will show db2sysc process consuming up to 100% CPU. Using 'db2pd -edus' will reveal a single thread/EDU consuming most/all CPU time within the db2sysc process. A db2trc of this EDU will show it is looping in the following two functions: pdDiagGetNextRecordFromBuffer pdDiagReadFromFileIntoBufferBS | |

Truncate the current db2diag.log file by executing '> db2diag.log'. This will break the loop and result in SQL1042C being returned by the EDU. | |
