[Duplicity-talk] webdavs and large sync volume failing

[address@hidden]

Hi,

I am trying to use Duplicity and duply to backup appr 60GB data to webdavs 
storage.

The script is running on a raspberrypi with raspbian jessie

Small backups are working.
I have tried to run this backup in one go, it failed; I then split into 15GB 
chunks it failed again with exit code 137

Any ideas what to do / where to look for?
Is the webdavs access not stable enough for such backup?
Is it maybe a performance issue with the raspberry

btw I started the backup script via a cron job, it was then running several 
hours before it failed.

Thanks for help.

copy from the output:
