[R] Crash with seasonal ARIMA

[David James]

The following command crashes my Mac OS X version of R:
(I'm running R on a PowerMac G5, with 1 GB of RAM and dual processors.)

 > arima.0 <- arima(w3.ts,order=c(1,0,0),seasonal=list(order=c 
(1,0,0),period=365))

Here is some background:

w3.ts is hourly temperature data with about 20% NA's.  It contains  
about 3.5 years of data.

I am using period = 365, which makes sense me to me.  Is this wrong?
