ioerror means there was an I/O error, which may mean that the disk is full, or there was some other problem. Try using a lower resolution ('density' in IM terms I think). Given that you have 8 pages, each page is 32x76 inches and you have a resolution of 300 dpi you are looking at producing a lot of data, about 1.8Gb if depth=8 means greyscale.

There could be any number of other reasons why there was an ioerror, the next thing to do is to try a more recent version of Ghostscript 8.70 is now 6 years old..... As Mark Setchell suggests you could also try using a more recent version of ImageMagick, though I doubt that will help, since its clearly an error being returned from Ghostscript.
