Hello Jeff, You problem is interesting to me ! Rdiff-backup doesn't have the tendency to use alot of memory (it rarely reach 100MB on my systems). It is surprising to see an out or memory error like this in rdiff-backup.
May you provide some information revargin your current environment: 1. How many memory free you have 2. May you describes how big it the stuff you are trying to backup (nb files, average file size, etc.) 3. x86 or x86_64 ? 4. What is you python version ? Can you get your hand on the server logs too ? Causes it fail when requesting stuff from remote server... -- Patrik Dufresne Service Logiciel inc. http://www.patrikdufresne.com <http://patrikdufresne.com/>/ 514-971-6442 1-114 rue des Hautbois, St-Colomban, QC J5K 2H6 On Thu, Jun 9, 2016 at 6:54 PM, Jeff White <jeff.wh...@wsu.edu> wrote: > I'm trying to get rdiff-backup working for the first time across SSH (with > sudo) on two CentOS 7 hosts.
