Status: action was resumed (used for reporting).
This means a previously suspended action has recovered. Recovery happens e.g. when the action can reconnect to a server or some resource starvation is solved. This is an informational message telling you rsyslog now executes the action again.
Note: due to a bug in old rsyslog versions (e.g. 8.24.0) an “action was suspended” message is not necessarily reported. Thus the resumption message may be the only way to detect something went wrong. Version 8.1904.0 and above will much more reliably report action suspension.
