This is a known problem of rpm < 4.7. Huge amount of files - especially with 
the same basename (which shouldn't be the case here if I understood you 
right) - lead to intermediate data and rpmdb requests of #files square size. 
This can easily lead to memory usage beyond the 2GB address space or the 
memory of even a good equipped 64bit machine. Unfortunately removing the 
package takes even about double the memory... Runtime usage also gets out of 
hand as you are experiencing.

Your only chance is trying a more recent rpm version which has this problem 
fixed.
