When the CURRENT state of the resource is set from "TIMEOUT" to the actual state using the SSM RESET command, SSM will not execute the POST event actions (MATCH action taken when the resource is UP) even after having proper ACTION table entries.
This is working as designed. When the SSM RESET action is executed it sets the current state of the resource to UNKNOWN which triggers the SSMSTATE rule to detect the actual state of the resource. This process is not supposed to trigger the MATCH actions as it would cause executions even when it was not the first activation of the resource.
