https://answers.launchpad.net/duplicity/+question/658653

Hi team

I have used the duplicity for backup my server files few months before.  Currently I have upgraded the new version(0.7.14), the manifest cache file written in large size(near to GBs) due to bulk delete or changes. 

It was stopped the backup with this error - "OSError: [Errno 12] Cannot allocate memory". 

Please help me on this. Is there any way to solve this problem? 

Herewith  I have placed the logged error information for your reference.
