does not look 2.6 related but.. what machine is that? (there's a known TLS bug
on i386) also.. does it work with 2.4? (mmap is 2.x independant)

uh? this looks strange... are you sure the app uses 2.6 libc? the modify_ldt
should be used only with 2.4. it might be the case that the app is trying to use
statically linked old libc or something..
