Mini core dumps
FTOS supports mini core dumps on the for application and kernel crashes. The mini core dump apply 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 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<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 14-18 and sample file text is shown in Figure 14-19.
Figure 14-18. Mini application core file naming example
When a member or standby unit crashes, the mini core file gets uploaded to master unit. When the master
unit crashes, the mini core file is uploaded to new master.
