Problem IC84499
|
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 / A10 - 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() |
