'Extreme' version of MixSiar model produces an error.

[Edward-Doherty]

Dear Brian,

I hope everything is going well. I am trying to run a MixSiar model to estimate consumer diet and have ramped up the run times to improve model convergence. After running a model with a ‘very long’ setup, convergence is still poor: out of 1487 variables: 1249 > 1.01; 818 > 1.05; 537 > 1.1. I therefore ran an ‘extreme’ model, which takes about 1.5 weeks to run. However, when the model progress reaches 80%, it generates an error and aborts the run. It has done this twice and the error seems to be exclusive to the ‘extreme' model setup. I have attached a screenshot of the error. Do you have any idea what could be causing this and can you recommend a solution? Happy to provide more details on the model setup, code, data, etc. if you need it.

Best wishes, Ed
