Re: [Duplicity-talk] OSError: [Errno 35] Resource temporarily unavailable

[edgar . soldin]

this really smells like all the gpg processes keep hanging around an python 
cannot get/deliver more file handlers.

see
http://article.gmane.org/gmane.comp.sysutils.backup.duplicity.general/3630/match=resource+temporarily+unavailable

we have a solution for linux. but that seems not to work under mac osx as in 
your case.

btw. your backup chain is really really really long. you should consider doing 
fulls from time to time, which circumvents the error above and has teh 
advantage that not every chain gets corrupted becuase one volume might be.

could you try restoring on a machine with more ram OR raise the setting for 
open file descriptors on osx (ulimit n reports 256 on an osx here).
