show context Command
The show context command displays core dump context information for the last ten core dumps. The
command output is used for post-analysis in the debugging of processes (determine if any process
crashes have occurred).
If there are no crashed processes, the show context command displays no output for each node. The
following example shows the output of the show context command with no crashed processes.
