Application and kernel mini core dumps are always enabled. The mini core dumps contain the stack space and some other very minimal information that can be used 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..acore.mini.txt. The kernel mini core file name format is f10StkUnit.kcore.mini.txt. Sample files names are shown in Figure 46-12 and sample file text is shown in Figure 46-13. Figure 46-12.
