I was able to diagnose the problem using your server, and unfortunately, this is due to the same nVidia driver issues previously described. When VirtualGL is preloaded by vglrun, it also loads libGL.so into memory, and this causes nVidia's custom versions of dlsym() and dlopen() to override the ones in libdl. Thus, applications that try to use dlsym() (which unfortunately includes /bin/sh in this case) will sometimes fail. You can reproduce the same failure without even invoking vglrun:
