Karl Wright commented on CONNECTORS-897:
----------------------------------------
All I can tell from this is that it is coming from HttpClient when it is trying
to deal with chunked IO. HttpClient is called by the SolrJ library. The SolrJ
library is called by the Solr output connector. So it's pretty far down in the
chain of what is going on.
My suspicion, since nobody else has reported this, is that your solr instance
(or the app server it is running under) is configured to reject posts that are
too large, and that these respond with some bit of HTML that HttpClient of
course does not recognize as a valid response to a chunked request. (I believe
this is actually the default configuration for later versions of Solr.) But
the only way to really debug it is to turn on HttpClient wire debugging and
crawl one of the affected documents. You do this by editing logging.ini and
adding lines pertaining to HttpClient. Google "HttpClient wire debugging" and
you should get documentation.
If it is not obvious from the logs what is going on, please let us know.

> Project: ManifoldCF
> Issue Type: Bug
> Components: CMIS connector
> Affects Versions: ManifoldCF 1.4.1
> Environment: Windows 7 with bundled mcf 1.4.1, solr 4.6
> Reporter: lalit
>
> Hi,
> I have downloaded mcf(ManifoldCF) 1.4.1 source from tag site & build it as
> per instructions. Now i am using cmis connector to connect to alfresco repo &
> using solr as output channel.
> When i am crawling alfresco repo for indexing into solr, whenever mcf crawls
> any media such as image or video, i am getting this error into mcf logs. I
> have also added adm4.1.jar & xmpcore.jar into ..\contrib\extraction\lib.
