A Dtrace of the w3wp process on the SharePoint Frontend server will show the following:

This issue is caused by the archive having more than 5 index volumes on the Enterprise Vault (EV) server.  The search by default is only able to search 5 or fewer index volumes.  

A modification can be made to <Install_Path>\Program Files (x86)\Enterprise Vault\EvSharePointArchiveTask.exe.config on the EV server to allow for a higher number of volumes to be searched.  An example of the configuration updates can be found in <Install_Path>\Program Files (x86)\Enterprise Vault\Example EvSharePointArchiveTask.exe.config

1. Open Notepad as Administrator on the EV server.  

2. Go to File > Open and open the <Install_Path>\Program Files (x86)\Enterprise Vault\EvSharePointArchiveTask.exe.config file.  

3. The sections in bold must be added to the file to modify the MaxSearchIndexVolumeSets setting.  These settings may or may not exist in the file already.  In this case the value has been increased from 5 to 20.  

4. Run the SharePoint archiving task to update the configuration setting on the target SharePoint site.  

These steps should allow the Version History to search up to 20 index volumes without returning an error.
