Problem IC65073
|
Status: Geschlossen |
SET WRITE SUSPEND AND RESUME CAN DEADLOCK WITH A BLOCKED TABLE EVENT MONITOR |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
SET WRITE RESUME will hang forever in the following stack,
waiting on dblatch:
sqloXlatchConflict - 0x70
sqlbSetWriteResume__FP12SQLB_GLOBALSbP5sqlcaiPUs + 0x920
sqlbSetWriteAction__FP12SQLB_GLOBALSClCbP5sqlcaCiPUs + 0xDC
sqlbSetPoolChange__FP5sqldaT1P5sqlca + 0x460
sqlerKnownProcedure__FiPcPiP5sqldaT4P13sqlerFmpTable + 0x3EC
sqlerCallDL__FP14db2UCinterfaceP9UCstpInfo + 0x64C
sqljs_ddm_excsqlstt__FP14db2UCinterfaceP13sqljDDMObject + 0xA8
...
The dblatch is held by an agent doing a flush event monitor,
waiting on em_list_latch:
sqloXlatchConflict - 0x70
sqloXlatchConflict@glue15D + 0x74
flush_monitor__13sqm_evmon_mgrFPC9sqlm_empdCUc + 0x474
flush_event_monitor__13sqm_evmon_mgrFPC9sqlm_empdCUi + 0x130
sqlrlfem__FP8sqlrr_cbPUcUsUc + 0x260
sqlnq_flush_evmon_stmt__FPP8stknode_i10actiontypePU + 0x168
...
The em_list_latch is held by an agent trying to write an event
to a buffer. The event monitor itself is not able to write out a
full buffer to the database, because of the write suspend state. |
