MATLAB is running out of memory (or swap), not disk space in your working directory. John summarised the possible causes of 'out of memory' messages during realign in the message archived at http://www.mailbase.ac.uk/lists/spm/1999-12/0185.html which might be helpful. If this doesn't solve your problem, then could you provide more details of the machine you are using, the memory and swap space available, and the number and type of files you are trying to realign.
