<div class="gmail_quote"><div>Hey,</div><div> </div><div> First of all do not use different values of radt for different domains. I suppose they should be same. Keep 30 if possible. The problem looks like due to the memory or input data. You can use 'ulimit -s unlimited' to avoid memory problem. However, I am not sure about whether you are inputing the data properly or not. Please check that part carefully. These are my suggestions!</div>

Many of my 5.5-day inits run OK, but a few here and there are crashing. Here's an example of the frustrating lack of details:<br>

It's repeatable. Happens whether I use adaptive time stepping or not. Happens whether I use OBS nudging or not.<br>
<br>
Any suggestions for how to track down this error?<br>
