Mark Miller commented on SOLR-8933:
-----------------------------------

SingleThreadedJsonLoader looks like it's off?

{code}
      try {
        // We won't close this stream because it belongs to ServletContainer Request
        Reader reader = stream.getReader();
        if (log.isTraceEnabled()) {
          String body = IOUtils.toString(reader);
          log.trace("body", body);
          reader = new StringReader(body);
        }

        this.processUpdate(reader);
      } catch (ParseException e) {
        throw new SolrException(SolrException.ErrorCode.BAD_REQUEST, "Cannot parse provided JSON: " + e.getMessage());
      }
      
      parser = new JSONParser(reader);
      this.processUpdate();
    }
{code}

> After SOLR-8453 we started seeing some IOExceptions coming out of SolrDispatchFilter with "Stream Closed" messages.
> It looks like we are indeed closing the request stream in several places when we really need to be letting the web container handle their life cycle. I've got a preliminary patch ready and am working on testing it to make sure there are no regressions.
> A very strange piece of this is that I have been entirely unable to reproduce it on a unit test, but have seen it on cluster deployment quite consistently.
