Severity: 3-Major


vcmpd may crash when it is exiting. The system logs an error message similar to the following in /var/log/ltm: err vcmpd[14604]: 01510000:3: Uncaught exception: basic_string::_S_create It's possible that vcmpd will then not start up, logging errors similar to the following in /var/log/ltm: umount(/var/tmstat-vcmp/<guest name>) failed: (16, Device or resource busy


vcmpd cores, but does so when already exiting. It is possible that vcmpd will then be unable to restart itself, and will need to be manually restarted.


vCMP must be in use.


If vcmpd cannot restart itself, you can manually restart it by running the following command: tmsh restart sys service vcmpd
