Voice Gateway Media Card maintenance Page 753 of 910
IP Line Description, Installation and Maintenance
If the audit task finds a suspended task, it performs the following actions:
• outputs a stack and register dump to the debug port
• outputs a file on the /C: drive
• resets the card
This function provides an automatic way to return the card to service and
provides critical debug information. The information is output to the
EXCPLOG.n files (where n is a number from 0-3) that are located in the
/C:/LOG directory. The new information is placed in these files where it
cannot be overwritten by the usual information output to the SYSLOG file
when the card reboots.
The auditRebootSet command disables the card reboot if any task is found
in a suspended state.
The maintenance audit enhancement differentiates between tasks that are
critical and non-critical.
• A critical task is any task that the IP Line application needs to function.
When a critical task is not functioning properly, it causes noticeable
degradation in the IP Line application.
• A non-critical task is any other task that does not cause noticeable
degradation to the IP Line application.
If a critical task is found suspended, the stack and register information is
dumped and the card is then reset. If a task on the critical task list disappears,
it is treated as a suspended task. Therefore, a missing critical task triggers a
reboot and a missing non-critical task does not trigger a reboot.
If a non-critical task is found suspended, the information is dumped but the
card is not reset. The card is reset when the Voice Gateway Media Card clock
reaches 2:00 a.m. (default reset time). The reset time is configured from the
CLI. This eliminates card resets that impact service for non-critical tasks by
delaying them to a non-service impacting time.
