CumulusMX Freezing
Posted: Sun 17 May 2020 3:50 pm
Hi all,
I have been running CumulusMX for a few months now and have found it much better than Cumulus V1, V1 I ran for many years. However, in the time I have been running MX I have noted that it had frozen a number of times i.e. the green arrow pointer with in the Last cumulus / station update status changing to red down arrow mostly the last station update. And the only way I have been able to restart is by closing and restarting CumulusMX Version 3.5.4 3075. Yes, I will be updating in due course.
Examining the MXdiags log files I found that I had a number of issues that I have sorted and it has pointed me to the CumulusMX freezing issue as this is being flagged as *** Data input appears to have stopped. I have attached file 20200516-200855.txt. As CumulusMX had been running OK at 2020-05-17 11:31:58 I trayed an experiment to see how CumulusMX would handle the removal of the data etc from my Davis vantage pro weather envoy this I did at 11:31 and as can be seen below how CumulusMX is seeing this condition at ~11:33 the data was reconnected but CumulusMX did not see this and would not respond correctly i.e. did not start responding until I stopped the programme and restarted, which are the same symptoms that I have been experiencing .
2020-05-17 11:31:58.234 !!! loop data not received, bytes received = 0
2020-05-17 11:33:00.626 *** Data input appears to have stopped
2020-05-17 11:34:00.018 *** Data input appears to have stopped
2020-05-17 11:35:00.317 *** Data input appears to have stopped
2020-05-17 11:36:00.709 *** Data input appears to have stopped
2020-05-17 11:37:00.039 *** Data input appears to have stopped
2020-05-17 11:38:00.479 *** Data input appears to have stopped
Exiting system due to external CTRL-C, or process kill, or shutdown
So, my questions are: -
1. As I am running a Davis Vantage Pro with an early firmware version with LOOP2 disabled I am disregarding any references in the log files to “No ack received in response to LOOP 20” and “!!! VP2 Not woken” is this correct?
2. In Cumulus V1 following clicking on the red indicator within the Error status area, I do recall intermittently see reference to either an FTP issue i.e. not been able to connect or a comment relating to data not being received, however neither of these adversely affect the operation of the programme. In view of the above how does CumulusMX handle the restarting of the programme following lost data, also is the status of “*** Data input appears to have stopped” only relating to external data?
3. What is the meaning of “loop data not received,” status as within some attached logs it is indicating that it can recover if identified? The logs also indicate different bytes counts have been received?
