Cisco Bug: CSCtc97803 - NPE crashed after LC crash
May 13, 2010
- Cisco uBR7200 Series Universal Broadband Routers
Known Affected Releases
Symptom: On ubr7k, NPE crashed after LC crashed. Conditions: When copying config to running config, NPE was processing configs, at the same time, LC crashed. In the NPE CLI command function, it might suspend the 'Exec' process because of calling of printf(). Meanwhile, LC crashing triggered an OIR interrupt, and OIR detaching process might get the chance of running, as Exec process was suspended. The OIR detaching process would free hwidb->ds, so when Exec process resumed, if it accessed hwidb->ds again, NPE crashed.
