rsync - Feb 2011 - The problems with rsync continues. (code 255)

Hi there:

As I posted a few days ago I have problems rsyncing two machines. I will add
more logs to this e-mail hoping someone could help me.
I'm doing a daily backup calling a shell script from cron as root. 
This is the log of the shell script:

As you can see seems to be a timeout problem cause the timeout arrises 21
seconds after the command is invoked.
But why this happens in some paths and not in others?
The paths are always the same paths (from day to day).
What can I do? Where can I change timeouts?

Any help will be  appreciated, cause this is getting me crazy.

Thanks in advance:

No, they're not.
In the first log you showed a couple of days ago it was only the clamav
path that failed (I don't see that one now).
That time /var/spool/exim succeeded, now it fails, for example.

As I said before: it's not an rsync issue, ssh fails to connect, hence
it's network related, e.g. a firewall that doesn't work correctly.
