Mini Core Dumps
Dell Networking OS supports mini core dumps on the application and kernel crashes.
Application and kernel mini core dumps are always enabled. The mini core dumps contain the stack
space and some other 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 filename format is f10StkUnit<Stack_unit_no>.<Application
name>.acore.mini.txt. The kernel mini core filename format is f10StkUnit<Stack_unit_no>.kcore.mini.txt.
The following are sample filenames.
The panic string contains key information regarding the crash. Several panic string types exist, and they
are displayed in regular English text to enable easier understanding of the crash cause.
