Description

On all 7.x versions (fixed in 8.0.0), when set up for auto failover, a BIG-IQ Data Collection Device (DCD) cluster member that receives an undisclosed message may cause the corosync process to abort.

Note: Software versions which have reached End of Software Development (EoSD) are not evaluated.
