Hi.

I'm getting this error each ten minutes. Is realted to a job to machien learning. Do anyone knows what is happening? How can I fix it?

Thank you.

Hi,

would it be possible for you to provide us with a couple of pieces of information?

  • what version of the Elastic stack are you running?
  • what are the details of the job configuration?

Also, it would help us immensely if you could provide us with an (anonymised) data set that reproduces the problem.

In the mean time we'll review our code and investigate.

Thanks,

Ed

Hi,

I've opened https://github.com/elastic/ml-cpp/issues/364 to track this issue. As mentioned, any further information you can provide to help us get to the bottom of this would be greatly appreciated,

Thanks,

Ed
