This is 6.5-current on an old ALIX (dmesg bellow).
I am syncing its backups to a remote machine with openrsync.
It works on all files except one that is big:
196M /backup/gw.stare.cz/dump.home.0
32.0K /backup/gw.stare.cz/dump.home.1
32.0K /backup/gw.stare.cz/dump.home.2

64.0K /backup/gw.stare.cz/dump.home.4

64.0K /backup/gw.stare.cz/dump.root.3
64.0K /backup/gw.stare.cz/dump.root.4
10.2M /backup/gw.stare.cz/dump.var.0
2.1M /backup/gw.stare.cz/dump.var.1
2.1M /backup/gw.stare.cz/dump.var.2
2.1M /backup/gw.stare.cz/dump.var.3
2.2M /backup/gw.stare.cz/dump.var.4
1.6G /backup/gw.stare.cz/dump.var.log.0
$ openrsync -av --del /backup/gw.stare.cz/ remote:/backup/gw.stare.cz
(sits there for a long time once it gets to the big file)
/usr/src/usr.bin/rsync/sender.c:550: error: /backup/gw.stare.cz/dump.var.log.0:
mmap: Cannot allocate memory
/usr/src/usr.bin/rsync/client.c:86: error: rsync_sender
According to ktrace,
66400 openrsync STRU struct stat { dev=9, ino=16224, mode=-rw------- , nlink=1

66400 openrsync RET mmap -1 errno 12 Cannot allocate memory
Does that mean openrsync tries to mmap() the entire file?
The machine only has 256MB of memory, but it does transfer
a test file of 300MB, so that can't be it.
