Problem IC81831 | Status: Geschlossen |
DB2 PAGE CLEANERS MAY RECEIVE SIG 11 WHEN 'DB2_USE_ALTERNATE_PAG E_CLEANING=ON' AND 'SET WRITE SUSPEND/RESUME' IS USED | |
Produkt: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
Problembeschreibung: | |
While the cleaner was handling the pages list, a 'set write suspend' came in and prevented pages to be written. This sent the cleaner into sleep. When it resumes after a 'set write resume' has been issued, it assumes the current list can only be a dirty list. Such that the page cleaner will trap with invalid pointer access. The trap file would show a stack trace similar to the one below .sqlbClnrCheckAndPause.fdpr.clone.1805__FP12SQLB_CLNR_CBPb + 0x2B8 sqlbClnrEntryPoint__FP12sqbPgClnrEdu + 0xD28 sqlbClnrEntryPoint__FP12sqbPgClnrEdu + 0x24 RunEDU__12sqbPgClnrEduFv + 0x34 __9sqzEDUObjFv + 0x1F0 sqloEDUEntry + 0x260 It might vary because of the way the compiler generated the code. The real stack, however, should be the following (only showing the top part): sqlbClnrCheckAndPause() sqlbClnrFindWork() sqlbClnrEntryPoint() sqbPgClnrEdu::RunEDU() | |
