Random Crashes On Pi

[mintwurm]

I'm using a raspberry pi as a server for sync.
The pi itself is quite stable. It has been running for over a month without a crash. Each midnight a cronjob reboots the system and that never failed. Upon restart, another cronjob starts btsync. But sometimes in the evening the pi would vanish from the list of peers. Now the issue has become so annoying that I checked the logs. Here is the error message:

DNBA5BM4RYHCNN6A]: error: CheckOriginalFile: No such file or directory (2)

Can you read this ? Is this a problem with sync or with the pi ?

mintwurm,

 

What version of Sync is it exactly? we'll look it up.

So far, try changing its listening port.

[mintwurm]

It's sync 2.3 installed from the .deb package for the pi.

I'll try to change the listening port.

Thank you

I changed the port (of the webui) , so far there was no crash, but the log still contains lots of error messages:

this error occurs at 10:40, 10:20, 9:20, 8:30

I changed the listening port of the web-ui but that doesn't affect the ports btsync uses for transfer, does it ? I know that in the config file you can specify other ports but I'm not running btsync with a config and have made the experience that connecting an existing, already configured, sync instance with a config file will prompt you to create a new id and deletes existing shares.

 

therefore three new questions: Can I dump not a sample config but instead the current config. Can I start btsync with a config file without deleting my id ? Can I change the listening port without a config file.

The "Unknown result code (UPnP protocol violation?)" message whilst trying to map a port would indicate an issue with your router.

I'd suggest manually opening a port on your router for Sync to use, and then specify this port in sync's configuration file (rather than using uPnP to automatically open/map a port on your router). i.e. set "use_upnp" to "false", and "listening_port" to the port number you've manually opened on your router.

Thanks for the quick answer.

I know how to open ports on my router.

But the only workflow I know to get them configured into sync is this :

1. dump sample config
2. adapt sample config
3. start sync with --config flag and path to config file

In the past this has caused sync to prompt me for a new identity and to delete previous settings. That would be fatal.

Is there a way to export the current config, adapt the port without a config file or register a config file without deleting my previous settings ?

 

And do you have news on the error that lead to an actual crash ? The failed assert in the first log ?

[Helen]

mintwurm,

That is not a critical error and shall not the the cause of the crash. 

Can you please submit the full log, and crash dump to support? Thanks. See if you already have any dmp files in storage (near the logs). thanks.

Yes, you can use config and there point Sync to your current "storage" ("storage_path"), but if you're not sure, don't use config.
