Hi,  
I am repeatedly getting the following error when I run my stan() function. Please help to overcome the error.  
‘ **R session Aborted. R encountered a fatal error. The session was terminated** ’

If your question relates to installation please provide the following information:

- Operating System = Windows 10
- RStan Version = 2.18.2

I have been using RCloud to run Rstan before changing to Windows desktop. But often using Cloud gives me an error regarding out of memory and had to change to Windows desktop.

I would really appreciate your help

Can you tell us what the Stan program is? Are you sure it did not run out of RAM? Was this with or without first doing `Sys.setenv(LOCAL_CPP = "-mtune = native")`? Etc.

Also, it would be better if you upgraded the **rstan** 2.18.2 on CRAN, although that may not fix this issue.

Thanks for the quick reply.  
My stan program is as follows

```stan

//This is stan code for simulating fake data 

  functions {
     real[] ode(real t,
     real[] y,
     real[] params,
     real[] x_r, // x_r:real data, x_i: integer data
     int[] x_i) {

     real dydt[6];
    
     real A;
     real beta;
     real delta;
     real gamma;
     real omega;
     real sigma;
     real kappa;
     real eta;
     delta =params[1]; 
     A = x_r[1];
     beta = x_r[2];
     gamma = x_r[3];
     omega = x_r[4];
     sigma = x_r[5];
     kappa = x_r[6];
     eta = x_r[7];
     
     dydt[1] = A - beta * y[5] * y[1] - beta * y[6] * y[1];                 
     dydt[2] = beta * y[1] * y[5] - beta * y[6] * y[2]- delta * y[2];      
     dydt[3] = beta * y[6] * y[1] - beta * y[5] * y[3] ;                   
     dydt[4]= beta * y[6] * y[2] + beta * y[5] * y[3] - gamma * y[4];        
     dydt[5] = omega * y[2] + omega * (1-sigma) * y[4] - kappa * y[5];          
     dydt[6] = eta * sigma* y[4] - kappa * y[6];                         
    
  return dydt;
 }

}

data {
    int<lower=1> T; //max time
     real y0[6]; //initial condition of ode
     real t0; //initial time
     real ts[T]; //time span
     real A;
     real beta;
     real delta;
     real gamma;
     real omega;
     real sigma;
     real kappa;
     real eta;
}

transformed data {
      real params[1];
      real x_r[7];
      int x_i[0];
     
      params[1] = delta;
      x_r[1] = A;
      x_r[2] = beta;
      x_r[3] = gamma;
      x_r[4]= omega;
      x_r[5]= sigma;
      x_r[6] = kappa;
      x_r[7] = eta;
}
model {
  
}
generated quantities {
     real y_hat[T,6];
     y_hat = integrate_ode_bdf(ode, y0, t0, ts, params, x_r, x_i);
// generate fake data and add measurement error
   for (t in 1:T) {
   y_hat[t,1] = y_hat[t,1] + normal_rng(0, 0.1);
   y_hat[t,2] = y_hat[t,2] + normal_rng(0, 0.1);
   y_hat[t,3] = y_hat[t,3] + normal_rng(0, 0.1);
   y_hat[t,4] = y_hat[t,4] + normal_rng(0, 0.1);
   y_hat[t,5] = y_hat[t,5] + normal_rng(0, 0.1);
   y_hat[t,6] = y_hat[t,6] + normal_rng(0, 0.1);
  }
}

```

And R code used to run the stan program is

```R
#use typical values to simulate fake data from ode
sim_data <- list(T = 10, y0 = c(1e8, 0, 0, 0, 1, 1), t0 = 0,
                 ts = 1:10,
                 A= 1.4e6, beta = 3.8e-11, delta =3.3, gamma = 0.14, omega = 1e4, sigma = 0.5, kappa = 3.5, eta = 20000)

#simulate fake data using the system of ODEs
fit1 <- stan("myModel-sim.stan", data = sim_data,
             chains = 1, iter = 1,
             algorithm = "Fixed_param")

```

When I ran this on RCloud it gave me the following error, which I think says ran out of RAM as you said.

```R
Error in compileCode(f, code, language = language, verbose = verbose) : 
  Compilation ERROR, function(s)/method(s) not created! clang: error: unable to execute command: Killed

```

The stan program worked fine in RCloud early today. The error from Cloud is given after using Cloud for sometime most of the days.

The error from desktop is given without using  
Sys.setenv(LOCAL\_CPP = “-mtune = native”)

Thanks

This looks similar to a crash we saw on Windows last week when using `algebra_solver`. Unfortunately, we have not figured out why it is happening yet. RStudio Cloud will probably work at this time of night.

@bgoodri ,  
I am trying to run the above stan code from RCloud today and still getting the above error regarding CompileCode. Is there anyway I could overcome this error. Please help. I really need to speedup my simulation, and most of the time getting the CompileCode error is slowing down things.

Thanks

I still haven’t figured out the Windows bug, but I can get the example to compile on RStudio Cloud now (which has recently upgraded its compiler).

I had to add

```
LDFLAGS += -fuse-ld=gold

```

to the Makevars\_Stan file in addition to changing the CXX\* lines from `clang++` to `clang++-5.0` and adding `-flto=thin` to the CXX\*FLAGS lines.

Thanks @bgoodri .

I can run the code on desktop (Windows 10) but using _integrate\_ode\_rk45()_ instead of _integrate\_ode\_bdf()_. I also had to use _Sys.setenv(LOCAL\_CPPFLAGS = ‘-march=native’)_ in the R file for the stan code to run.

@bgoodri  
Have you solved it now?

I installed rstan from [https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started](https://github.com/stan-dev/rstan/wiki/RStan-Getting-Started) (I think it is the latest), and run on **Windows 10**. I also got R session abort as shown below, even if I use only 1 chain, warmup=5, iter=10, and takes small memory.

Sometimes when running 4 chains in parallel, It said “Error reading from connection”.

However, the same code runs well on my **mac** system.

Thank you.

No, but anything that works serially but does not work in parallel is likely (if not due to running out of RAM) some sort of antivirus like thing that shuts a program down if it launches multiple threads.

@bgoodri  
R also aborts with 1 chain (no parallel).

Some of the ODE functions cause problems on Windows. Other than that, it is hard to say. Do the functions in **rstanarm** work? That would indicate whether there is a problem running compiled code on your machine.

It may take time to try.  
Before that, I found another interesting issue:

On another Windows computer, the first time runs well, while at the second time, R said

It looks as if your R code is failing you.

@bgoodri No, I know this NA happens somewhere outside stan sampling. That does not matter.

If you call `tempdir()` before calling `stan` or `sampling`, there might be something in one of the .txt files in that directory that has more information about the error.

Thanks.  
Later I just changed to linux server offered by my university, installing rstan per [https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Linux](https://github.com/stan-dev/rstan/wiki/Installing-RStan-on-Linux). Then it works well.

My problem is the same as yours. I tried to reinstall it, but I still couldn’t solve it. Have you solved it?
