Could it be that "cmd" is actually reporting the "Illegal Seek"? Make sure that your die() is not simply die $! but has something more telling such as: 
system("cmd &") && die "cmd failed: $!\n";

Note: system() returns 0 on success. If you have system() || die() you are trying to die on success. That, I'm assuming, would be bad.
