I upgraded by backtesting nodes to one capable of handling the memory load from 9 different universe searches going at once. Now running this I am receiving something I am not certain if is a bug or where to begin troubleshooting. See below.
Getting the following error:
[ERROR] FATAL UNHANDLED EXCEPTION: at System.Reflection.RuntimeModule.GetTypes(RuntimeModule module), at System.Reflection.Assembly.GetTypes(), at QuantConnect.Exceptions.StackExceptionInterpreter.<>c.<CreateFromAssemblies>b__10_0(Assembly assembly) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Exceptions/StackExceptionInterpreter.cs:line 120, at System.Linq.Enumerable.SelectManyIterator[TSource,TCollection,TResult](IEnumerable`1 source, Func`2 collectionSelector, Func`3 resultSelector)+MoveNext(), at System.Linq.Enumerable.WhereEnumerableIterator`1.ToArray(), at System.Linq.Buffer`1..ctor(IEnumerable`1 source), at System.Linq.OrderedEnumerable`1.GetEnumerator()+MoveNext(), at System.Linq.Enumerable.SelectIPartitionIterator`2.LazyToArray(), at System.Linq.Enumerable.SelectIPartitionIterator`2.ToArray(), at System.Linq.Buffer`1..ctor(IEnumerable`1 source), at System.Linq.OrderedEnumerable`1.ToList(), at QuantConnect.Exceptions.StackExceptionInterpreter..ctor(IEnumerable`1 interpreters) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Exceptions/StackExceptionInterpreter.cs:line 48, at QuantConnect.Exceptions.StackExceptionInterpreter.CreateFromAssemblies(IEnumerable`1 assemblies) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Exceptions/StackExceptionInterpreter.cs:line 133, at QuantConnect.Exceptions.StackExceptionInterpreter.<>c.<.cctor>b__12_0() in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Exceptions/StackExceptionInterpreter.cs:line 35, at System.Lazy`1.ViaFactory(LazyThreadSafetyMode mode),--- End of stack trace from previous location ---, at System.Lazy`1.CreateValue(), at QuantConnect.Extensions.SetRuntimeError(IAlgorithm algorithm, Exception exception, String context) in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Extensions.cs:line 3452, at QuantConnect.Lean.Engine.Engine.<>c__DisplayClass10_1.<Run>b__9() in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Engine/Engine.cs:line 336, at QuantConnect.Util.WorkerThread.<.ctor>b__7_0() in /LeanCloud/CI.Builder/bin/Debug/src/QuantConnect/Lean/Common/Util/WorkerThread.cs:line 62

Hi Axist
It seems like it was still the memory issue. We can run the above algorithm in a B8-16 node without error.
