On platforms with HSB, if an HSB lockup occurs, then TMM panics and generates a core file for post-analysis. HSB also triggers a nic_failsafe reboot. In certain cases, the reboot occurs before the core file is fully written, resulting in a truncated core.
The reboot happens after the core dump begins before it completes, resulting in a truncated core dump, which is not useful for analyzing why the HSB lockup occurred. Traffic disrupted while tmm restarts.
-- Any platform with HSB. -- An HSB lockup occurs, triggering a core dump and a nic_failsafe reboot.
None.
Reboot is delayed until TMM core file is completed.
