Hey everybody,
First of all, I wanted to say that this is my first time writing here. I
hope I don't do anything wrong.
I went to create the "bug" ticket and saw it would be a good idea to first
talk to some of you via IRC (didn't work for me or I did something wrong
after 20 years of not using it..)
I'm currently using Solr 8.1.1 in production and I use the Schema API to
create the necessary fields before starting to index my new data. (Reason,
the managed-schema would be big for me to take care of and I decided to
automate this process by using the REST API).
I started trying to upgrade* from 8.1.1* directly to *8.6.1* and the python
script I use to add some fields and analyzers started to *kill solr after
some successful processes to finish* without issues.
*Let's put it simply that I have to make sure the fields that contain the
word "blablabla" in it need to be deleted and then recreated. I have ~33 of
them.*
The script works as expected but after some successful creations it kills
Solr!
This script was implemented in python and I thought that I might have done
something that doesn't work with Solr 8.6.1 anymore and decided to test it
with the *proper implementation of the library in Java*, SolrJ 8.6.1 as
well. The same error occurred. I also didn't see any change in the
documentation with regards to the request I was making.
Unfortunately I don't have any stacktrace from Solr as there were no errors
popping up in the console for me. The only thing I see was the output of my
script, saying that the *Remote closed connection without response*:
...
Traceback (most recent call last):

With *Java and SolrJ* matching the Solr version I was using, I got this:

<http://localhost:32783/solr/my_core_name/schema?wt=javabin&version=2>*
Deleting field field_name_6
// REPEATS ALSO MANY TIMES
Maybe I need to run the same thing again with some different configuration
to help give you guys a hint on what the problem is?
To finalize, I started to go "back in time" to see when this happened and
realized that *I can only upgrade from 8.1.1. to 8.2.1* without this error
to happen. (I'm using the docker images in here btw:
https://github.com/docker-solr/docker-solr)
Thank you very much and I hope I can also help with this if it's really a
bug.
