Can you also post error log from the DONOR node and post relevant wsrep_* variables for further analysis

It seems that the server where this is running has a small space in RAM and when xtrabackup comes in to prepare a backup, it use to allocate 100MB RAM by default and consequently, failing by a lack of RAM space. It’s going to consider the size of dataset being copied to the backup set. Just to confirm, is this a small VM or similar thing?

Additionally, the fork() called out my attention: http://en.wikipedia.org/wiki/Fork_%28system_call%29

Cheers,

I had the same problem as you, I’ve solved enabling SWAP in the DONOR and other nodes.
