are you using the /Zm compiler option? we had to increase the amount of 
memory needed to compile the precompiled headers in VS2010.
oddly enough though, the help for the /Zm compiler option states:

If the compiler runs out of heap space and emits the C1060 error message when you use the /Zm compiler option, you might have reserved too much memory. Consider removing the /Zm option. If the 
compiler emits the C1076 error message, an accompanying C3859 message specifies the factor argument that you should use when you recompile your program with the /Zm compiler option

so either you're using a /Zm value which is too high, and you need to lower it, or vice versa. After a fair bit of mucking around, we settled on /Zm200 which works nicely, although you might need to 
change the /Zm factor for your usage/machine spec.
