Application Core Dumps
Application core dumps are disabled by default. A core dump file can be very large. Due to memory
requirements, the file can only be sent directly to an FTP server. It is not stored on the local flash. To
enable full application core dumps, use the
following command:
To undo this command, use the no logging coredump server command.
Mini Core Dumps
FTOS supports mini core dumps for application and kernel crashes. The mini core dump applies to Master,
Standby, and Member units.
Application and kernel mini core dumps are always enabled. The mini core dumps contain the stack space
and some other very minimal information that you can use to debug a crash. These files are small files and
are written into flash until space is exhausted. When the flash is full, the write process is stopped.
A mini core dump contains critical information in the event of a crash.
• Mini core dump files are located in
flash:/ (root dir).
• The application mini core file name format is
f10StkUnit<Stack_unit_no>.<Application
name
>.acore.mini.txt.
• The kernel mini core file name format is
f10StkUnit<Stack_unit_no>.kcore.mini.txt.
Sample files names are shown in Figure 22-19 and a sample file text is shown in Figure 22-20.
