Upon editing content with richtext datatypes I began getting these errors:

Error adding stylesheet to tinymce (id: 1173). System.NullReferenceException: Object reference not set to an instance of an object.    at umbraco.editorControls.tinyMCE3.TinyMCE..ctor(IData Data, String Configuration)     

and eventually the website would crash with this error:

Timeout expired.  The timeout period elapsed prior to obtaining a connection from the pool.  This may have occurred because all pooled connections were in use and max pool size was reached.   at System.Data.ProviderBase.DbConnectionFactory.GetConnection(DbConnection owningConnection)   at System.Data.ProviderBase.DbConnectionClosed.OpenConnection(DbConnection outerConnection, DbConnectionFactory connectionFactory)   at System.Data.SqlClient.SqlConnection.Open()  

I ran this sql query on the database before and after clicking on the suspected nodes and noticed they grew tenfold each time a node was accessed. When it hit > 100 the site crashed.

drop table #tempt     create table #tempt(spid int, ecid int ,status varchar(max),loginname varchar(max),hostname varchar(max),blk int,dbname varchar(max),cmd varchar(50),requestid int)   insert into #tempt exec spwhoselect COUNT(*),dbname from #tempt where dbname not in ('NULL','master','msdb')group by dbname

Not sure where to look from here. Any help would be greatly appreciated.
