Micro Queue is already full

Open skykep opened this issue 10 months ago • 8 comments

Current Behavior

At random times, the script will stop reading data from a 1756-L81E ControlLogix. The script also reads from a 1769-L32E and that data continues to read normally. This error occurred before the introduction of the controller manager, too.

From my PM2 log: 0|plc | 2023-08-29 07:26:16: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:16: Reading Error - Analog_Inputs[6] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:17: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:18: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:18: Reading Error - Discrete_Outputs[35].Out - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:19: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:20: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:21: Reading Error - F8[41] - TIMEOUT occurred while writing Reading Tag Group. 0|plc | 2023-08-29 07:26:22: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:23: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:23: Reading Error - Discrete_Outputs[35].Out - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:24: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:25: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:26: Reading Error - F8[41] - Micro Queue is already full at size of 100!!! 0|plc | 2023-08-29 07:26:26: Reading Error - Analog_Inputs[6] - Micro Queue is already full at size of 100!!!
