AHhh, ok. I was thinking that it was filling up the 1GB i allocated to it.

I just dropped the memory allocated to the instance down by about 10GB
and i'm still getting the error though.

 > free
              total       used       free     shared    buffers     cached
Mem:      34997288   32821828    2175460          0     227420   32541844

Swap:       530136         36     530100


seems like i've got 2GB free.

Food for thought..

I'll look more into it tomorrow morning though.

Thanks

Dave
