By raising this issue the indexing never completes.
What could be the issue here for the mime type and the core loading.
I am using 6.1.0 with sorlcloud in 3 instances with 3 zookeeper in each
instance.

Core reloads don't just happen. Something is requesting the reload.
If you are using options like the Managed Schema API, that can cause a
core reload, because a reload is necessary in order for a modified
config/schema to become active.
I've checked the update processor used by the data-driven example config
to modify the schema during indexing when unknown fields are
encountered. I did not see anything in that code that would cause a
reload, which makes sense, because a core reload in the middle of
indexing is a bad thing. Somebody would have noticed that, and we would
have fixed it.
There is some code or perhaps a person making a request that results in
a core or collection reload. A bug in Solr is *possible*, but I don't
think that's the problem here.
Another possibility is that one of your SolrCloud instances is getting
completely restarted ... but I think if that were happening, you'd
probably know about it.
Thanks,
Shawn
