If an attempt is made to subscribe to an unsupported telemetry sensor path on EX2300, EX3400, EX4000, EX4100 and EX4400 via gRPC, this causes the FPC to crash. This leads to a complete service outage until the module has automatically restarted.
The following log message can be seen when this issue happens:
agentd[<PID>]: AGENTD_RESOURCE_NOT_FOUND: No resource name found for <sensor>
This issue affects Junos OS on
EX2300, EX3400, EX4000, EX4100 and EX4400
