Interpreting Undeliverable Messages
Undeliverable messages, such as IMM, EVENT, and LOCAL, appear in the CSS
log when a queue on the CSS becomes full or overutilized to help clarify the
nature of the problem.
Undeliverable messages consist of a logging header and a logging message, as
shown in Figure 4-1.
Figure 4-1 Undeliverable Message Format
The logging header contains:
• A time stamp with the date and time
• The CSS slot and subslot number
• A logging sequence counter indicating that log messages were dropped due
to excessive logging or CSS processor load
• The subsystem and its log level
Figure 4-2 shows an example of a logging header.
