Hopefully someone can help, but to make sure you get a response post it in the Unrealscript area as well.

Does anyone else have any solutions to my problem?

[taz1004]

Not enough information. Your system spec, when did this problem start, did it ever successfully build before, what version of UDK...

[daem0nz]

intel core i5 2.66GHz
ATI RADEON EAH4890 1gb GDDR5
4GB RAM
150gb velociraptor HDD

it started after i put in a static mesh which i imported myself, most of my models have invalid lightmap co-ordinates but i was going to fix them after i finished the level. Yes it did build correctly before and it's the january 2012 version

Turns out one of my static meshes were causing the problem.

an old thread, but were you able to figure out what aspect of the static mesh was causing lightmass to crash? i'm getting this problem as well which most likely pertains to one skeletal mesh in the scene, since this is the only level that uses it, and only crashes on this level. not sure where to start troubleshooting this mesh, but the crash occurs in the log at 'job complete'
