Status: Closed |
RARE CONDITION COULD CAUSE A THREADSAFE FENCED ROUTINE REQUEST TO HANG |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Under a rare condition when executing threadsafe fenced
routines, the communication between the agent and the fenced
mode process could be out of sync, which leads to a hang in the
agent while it is holding the ipcLatch. This condition can only
happen when the routine is fenced, and threadsafe.
Agent's stack should look similar to below:
semop
sqloSSemP
sqlccipcrecv
sqlccrecv
sqlerMasterThreadReq
sqlerGetFmpThreadEntry |
