I'm trying to get rdiff-backup working for the first time across SSH
(with sudo) on two CentOS 7 hosts. I'm getting the following crash:
$ sudo rdiff-backup --restrict-read-only / -v5 --remote-schema 'ssh -l
rdiff -i /home/rdiff/.ssh/id_rsa -t -t %s "sudo /usr/bin/rdiff-backup
--server"' bacula-p1n01::/ /dumps/bacula-p1n01/

MemoryError
On that host when I strace the process I see:
[pid 11602] mmap(NULL, 18118029061677056, PROT_READ|PROT_WRITE,
MAP_PRIVATE|MAP_ANONYMOUS, -1, 0 <unfinished ...>
...
[pid 11602] <... mmap resumed> ) = -1 ENOMEM (Cannot allocate memory)
... am I mistaken or is rdiff-backup requesting a ridiculous amount of
memory? Why would it do that?
