SharePoint 2013 crawl error - The item may be too large or corrupt.

Question

When crawling SharePoint content I am getting the following error on two lists
"The item may be too large or corrupt. You may also verify that you have the latest version of this IFilter"
I have seen a couple of posts regarding this error in SharePoint 2010 and SharePoint 2007 but nothing for 2013. I tried the fix for SharePoint 2010 which was to modify the MaxDownloadSize property of the SearchApplication using Powershell (I increased
it from 64 to 128). This had no effect, although I think this property might relate to documents rather than lists.
The two lists that are throwing the errors have previously been indexed successfully, however since an index reset this error is happening, The first list had 6000+ items - I thought the fact the list is large might be causing the problem however
the other list only has 800+ items in it. Each item in the list has two rich text fields which have a fair bit of html in them but not loads.
Can anyone shed any light on this problem?
Thanks,
Neil

So, in SharePoint 2007 the fix was changing registry settings, in 2010 it was running a couple of Powershell commands.
The fix in 2013 - well we're back to changing registry settings!
This was the fix supplied by Microsoft - change the following registry settings
Key
Default   Value
New   Value
HKLM\SOFTWARE\Microsoft\Office   Server\15\Search\Global\GatheringManager\DedicatedFilterProcessMemoryQuota
104857600
209715200
HKLM\SOFTWARE\Microsoft\Office   Server\15\Search\Global\GatheringManager\FilterProcessMemoryQuota
104857600

SharePoint 2013 - a step forward?
