Symptoms

When BIG-IP restarts (bigstart restart), or when restjavad restarts (bigstart restart restjavad), there is an occasional crash of the icrd_child thread.

Impact

Occasional crash/SEGV exception.

Conditions

When BIG-IP restarts (bigstart restart), or when restjavad restarts. No other specific conditions.

Workaround

Restart restjavad (bigstart restart restjavad). Impact of workaround: The iControl REST API for making queries or modifications is temporarily unavailable while the restjavad service restarts.

Fix Information

Different approach of handling thread termination is implemented. New approach correctly terminates zombie processes and does not cause SEG fault.
