DB2 FOR LUW / DB2FORLUW / B10 - DB2

The db2_hang_detect script has a logic executing some monitor
commands like "list applications" in background mode and waiting
for its completion by checking the PID. If the command does not
end in a certain period, the script thinks it can be hanging and
kills the instance if ACTION=terminate. However, if the command
ends normally and another unrelated process in the system starts
with the same PID, db2_hang_detect thinks the command is still
running. Thus it may detect the hang incorrectly and kill the
instance. It can occur when the same PID is re-used within a
second and the process does not complete within the timeout
period.

It will be fixed on the next releases.

Using ACTION=INFORM instead of TERMINATE can prevent the
instance from being killed incorrectly

It will be fixed on the next releases.
