During operation, Boxcar status and error messages are written to the Boxcar log. By
default, messages are written using a waited write operation. Certain messages can be
written using a no-waited write operation, see BOXCAR-LOGMSGWRITEINTERVAL.
Error responses generated by the Network Security Processor in response to invalid
commands, are not logged by Boxcar, they are returned to the host application
process.
If the Boxcar log file fills up, an error 45 will be written to $0 whenever Boxcar attempts
to write a message to its log file. To prevent this situation, increase the MAXEXTENTS
parameter on the log file.
Queue Depth
Boxcar, using a no-waited write operation, creates a log entry whenever a queue depth
of two or more incoming requests, is cleared. The log entry states time when the queue
was cleared, how long the queue lasted, and the maximum number of incoming
requests that were queued. The example log entry below indicates that Boxcar queue
depth reached or exceeded 2 at 17:22:12, the queue cleared at 17:24:22 and the
maximum number of incoming queued requests was 6.
\CHIP.$BOXB: 30APR2009 17:24:22 Queue Depth = 6, cleared in 2
mins, 10 secs and 0 ms.
