We recently setup SolrCloud (Solr 4.10.3) with Sitecore 8.0 Update 2. We have also set it up so that it allows for Switch on Rebuild using this patch - https://github.com/SitecoreSupport/Sitecore.Support.449298/releases.
The setup works fine in one environment but in another environment it is throwing a strange error in the second environment. Some of the indexes rebuild fine but other indexes fail with the following error -

At first look, it looks like the error may be related to some corrupt BR tags without closing slash at the end. But where should I look is not clear.
Also, another issue is that after this happened, the content editor, index rebuild, and other interfaces have started failing with the same error.
Any help is appreciated.
Thanks
While going through the log files (of sitecore) I noticed more than 2K error entries for below. It's on CD server but the site seems to be running OK. I googled to see if anyone has faced this issue but no luck.

Appreciate if I can get help to resolve this.
The error says :
Could not find configuration node: databases/database[#id='master']
I ran into same type of error some time ago and it turns out that when you switch your references to master database toward web database on CD server, any indexing mechanics that uses master database must be turned off. In my case, I checked all config files related to Lucene indexes which somehow pointing to master database, like this:
<locations hint="list:AddCrawler">
<crawler type="Sitecore.ContentSearch.SitecoreItemCrawler, Sitecore.ContentSearch">
<Database>master</Database>
<Root>/sitecore</Root>
</crawler>
</locations>
There are several indexing config files which might use this pattern, including analytics and other extra features. I turned them off and the error disappeared.
I am trying to create an F# web service using OWIN, I have found 2 tutorials online and both are give me the same error of "Exception has been thrown by the target of an invocation" on the same line of code but I can not figure out why this is happening
use server = WebApp.Start<Startup>(baseAddress)
Below is a a short piece of code I am using the second and more complex example can be found here on the forfunandprofit website example number 3
namespace FSharpWebAPIOwin
open Owin

open System.Collections.Generic
open Microsoft.Owin.Hosting
