Opened: Mar 14, 2019
Severity: 2-Critical

Symptoms

Webroot daemon (wr_urldbd) crashes if it gets back to back SIGTERM signals. Subsequent SIGTERM is handled by default signal handler instead of registered one. As a result wr_urldbd's threads are not prevented from starting if wr_urldbd is in the process of shutting down.

Impact

Wr_urldbd crashes during restart and generates core file.

Conditions

-- System configuration is changing -- wr_urldbd is restarting continuously at the same time

Workaround

None.

Fix Information

Wr_urldbd handles all signals with registered handler and does not crash.
