3.0.1a2: Repeated connection denied

I get

cf3 Denying repeated connection from ...

from the server on the second copy if I try to copy more than one file using

files:
   "file1" copy_from => ...;
   "file2" copy_from => ...;

In the first case, cf-agent says

* Loaded /home/staff4/njkw/.cfagent/ppkeys/root-10.8.150.192.pub
*
...h.a.i.l.......................................................

and in the second

* Loaded /home/staff4/njkw/.cfagent/ppkeys/root-10.8.150.192.pub
* Couldn't send
* (send: Broken pipe)
* Couldn't send
* (send: Broken pipe)
* Couldn't send
* (send: Broken pipe)
* Challenge response from server gudea/10.8.150.192 was incorrect!
