DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
This problem occurs when:
-- you issue "get snapshot" command to retrieve "LOCK"
information like:
get snapshot for locks
get snapshot for applications
get snapshot for all
-- and there is some LOAD task running at the same time
As a result, the DB2 agent working on behalf of the "get
snapshot" command receives a SIGSEGV and DB2 instance crashes.
In the trap file for the DB2 agent which receives SIGSEGV, you
see call stack similar to the following:
=================================
sqlplGetLockWaitInfo
sqm_write_lock_waits
......
