Suddenly got disconnected from FTP server and rebooted

Hello
Below are my logs and back up file
As in the log, the flexy got disconnected with the FTP server at 10pm 04/05, and got back to normal after a reboot “Watchdog in process (timer)” (In the mean time, the FTP server and Flexy havent been changed, the FTP Server also still far from full)
Do you have any idea why this occur?

And this just happened this one time?

yes, but we and the customer want to know the cause

It is because you are sending too many FTP commands causing 501 (Server cannot accept argument) error responses.

Is there anyway to fix or avoid this?

It appears to be an issue with either the FTP command that you are sending or the FTP server that you are trying reach. The best way to fix it would be to determine why the server is sending that error, and eliminate the cause.

In the Flexy itself, you can adjust timeout parameters or use Passive mode.



These settings are in Setup > System > Storage > Edit SYSTEM cfg.

But why the Flexy reboot itself?

To reset everything and try to fix the problem.

Do you have any timers in your scripts?

You can also set this following value in config.txt (SYSTEM cfg) to a high value, like 3600, to avoid reboots:
