Opened: Jun 12, 2017

Severity: 2-Critical

Symptoms

The service dwbld restarts without generating any core dump. This might happen randomly.

Impact

The signal is uncaught by the process. The signal itself is safe to ignore, but when left uncaught causes the process to restart. Service restart can disrupt ip-intelligence functionality, which the dwbld supports.

Conditions

Certain dwbld socket operations can cause a signal to be issued.

Workaround

None.

Fix Information

None
