Big timeout time

[Fabian Cenedese]

Hi

I'm using rsync 3.0.3 on a NAS. In the parameter list I use --timeout=1800.
However sometimes I get very big timeout times like this one:

io timeout after 12220 seconds -- exiting
rsync error: timeout in data send/receive (code 30) at io.c(239) [sender=3.0.3pre1]

rsynd.conf on the receiving side only defines modules, no timing parameters.
How can that happen? What can I do to prevent this? As this is running on a
NAS it's not that easy to update rsync.

Thanks

bye  Fabi
