[torqueusers] Host key verification failed.

Jobs aren't exiting properly because the client node isn't able to copy 
the result back to the server node with scp.

I have two nodes. The server node is host3 and the client node is 
host13-3. Manually, I can ssh without password authentication these ways:

root at host3 -> root at host13-3
root at host3 -> user at host13-3
user at host3 -> user at host13-3
root at host13-3 -> user at host3
root at host13-3 -> root at host3
user at host13-3 -> user at host3

Still, I get the following error:

Unable to copy file /usr/spool/PBS/spool/110.host.OU to
+user at host3.cern.ch:/home/user/STDIN.o110
 >>> error from copy
Host key verification failed.
lost connection
 >>> end error output

This is debug output from pbs_mom on host13-3:

pbs_mom: sys_copy, command '/usr/bin/scp -Brp 
/usr/spool/PBS/spool/111.host.OU 
user at host3.cern.ch:/home/user/STDIN.o111' failed with status=1, giving 
up after 4 attempts

Any help would be appreciated
