Symptoms

The MDS 9000 switch experiences a callhome process crash after the `callhome test` command is issued, generating core files. If multiple `callhome test` commands are executed consecutively, such as `callhome test` followed by `callhome test-keepalive`, it can cause several service crashes potentially leading to an unexpected switch reboot.

switch-1(config-callhome)# destination-profile full_txt format xml

to this -
switch-1(config-callhome)# destination-profile full_txt
switch-1(config-callhome)# destination-profile full_txt format full-txt
