title: DynamoDb write batch, [WARN] (invoke@invoke.c:331 errno: No such file or directory) run_dotnet(dotnet_path, &args) failed
body: <p>I try to write batch to aws DynamoDb.
  Batch contains 15-20k elements and data is based on 30-40MB txt file.
  When I send small batches with &lt;14k elements, DynamoDb saves data and everything is OK.
  When I send 15-20k elements in batch, lambda makes multiple retries.
  After that lambda sends error:
  <strong>[WARN] (invoke@invoke.c:331 errno: No such file or directory) run_dotnet(dotnet_path, &amp;args) failed</strong></p>
  <p>I use c# sdk and crash appears on ExecuteAsync method.
  I tried to use try..catch.. to see something more meaningful, but I don't catch exception.
  I wonder what message: 'No such file or directory' means.
  Google doesn't give me answer to this kind of message exception.
  I wonder that It may be some limits on DynamoDb but it's difficult for me to see what limitation I try to exceed.
  Crashing-Files are not small and it could be the reason.</p>
  <p>Please help.</p>
