bigd crashes and generates a core file. The system logs entries in /var/log/ltm that are similar to the following: sod[5853]: 01140029:5: HA daemon_heartbeat bigd fails action is restart. This issue is more likely to occur if /var/log/ltm contains entries similar to the following: info bigd[5947]: reap_child: child process PID = 9198 exited with signal = 9.

External monitors that run for a long time and are killed by the next iteration of the monitor. For example, the LTM external monitor 'sample_monitor' contains logic to kill a running monitor if it runs too long.
None.
External monitors that run for a long time and are killed by the next iteration of the monitor now recover without bigd crashing and generating a core file.
bigd now logs child process exit messages in /var/log/bigdlog (so bigd.debug must be enabled) rather than in /var/log/ltm. This allows the logging to be controllable. Successful command exits are also logged for completeness since this the log messages only appears when debugging is enabled.
