The timeout may be coming from the plugin rather than nagios itself.   
For example, I occasional see check_by_ssh time out if packet loss  
gets a bit high, or if there's a DNS issue somewhere.  In that case,  
the timeout is set as part of the command line, and I've modified my  
check commands accordingly so that I can tune it:

define command {
     command_name    check_disk_remote
     command_line    $USER1$/check_by_ssh -H $HOSTADDRESS$ -t $USER4$ - 
C "$USER1$/check_disk -w $ARG1$ -c $ARG2$ -p $ARG3$"
}

The '-t' on check_by_ssh alters its timeout value.

Check the help for the plugins which you see reporting timeouts to see  
if you can tweak their timeout values.

HTH,
   Matt
