Re: [Duplicity-talk] pty.fork() failed: [Errno 12] Cannot allocate memory

[Igor Balic]

Thanks for the tip, patched util.py, memory stays low now. 
Backup is still running atm, but it seems it's stuck in a loop of some kind,
reading /etc/group and /etc/passwd files exclusively:

munmap(0x2b04520d4000, 64946176)        = 0
open("/etc/passwd", O_RDONLY)           = 17
fcntl(17, F_GETFD)                      = 0
fcntl(17, F_SETFD, FD_CLOEXEC)          = 0
fstat(17, {st_mode=S_IFREG|0644, st_size=4317, ...}) = 0
mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) =
0x2b04520d4000
read(17, "root:x:0:0:root:/root:/bin/bash\n"..., 4096) = 4096
close(17)                               = 0

I don't know if it's related. Any ideas?
