Severity: 3-Major


The iRules LX workspaces belong on only one device in a Device Service Cluster (DSC). If you have the same iRules LX workspace configured on multiple devices and then perform a config sync operation, the sdmd daemon cores.


The sdmd daemon cores. Although having multiple devices configured with the same iRules LX workspace is an incorrect configuration, sdmd should not core.


-- Multiple devices configured with the same iRules LX workspace in a DSC. -- Change one of the devices such that the configuration requires a config sync. -- Perform the config sync.


When the iRules LX workspace is correctly configured, i.e., on only one device in a DSC, there is no need to config sync, so this issues does not occur.
