umbraco6 - Umbraco V6.1.3 Lucene Index Corruption -

just upgraded umbraco v6.1.1 site v6.1.3. went on workstation. copied files web server after deleting there, did same database. set directory permissions , ran site. site (which mvc) runs 2 issues can't fathom , appreciate with.

one page errors read past eof error. view it's trying run. error on link in bold.

@inherits umbraco.web.mvc.umbracotemplatepage  @{     layout = "basepage.cshtml"; }           <div class="row-fluid">               <div class="span12">                   <h1>@umbraco.field("pagename")</h1>                   @umbraco.field("pagetext")               </div>             </div>           <div class="row-fluid">               <div class="span12">                 @foreach (var page in model.content.children) {                     <section class="well">                     <h3>@page.name</h3>                     @if(page.children.count() > 0) {                         <ul>                         **@foreach (var pub in page.children) {**                            <li><a href="@umbraco.media(pub.getpropertyvalue("publication")).url" title="@pub.name" target="_blank">@pub.name</a></li>                         }                         </ul>                     }                     </section>                 }                   </div>           </div> 

the stack trace is

[ioexception: read past eof]    lucene.net.index.findsegmentsfile.run(indexcommit commit) +2040    lucene.net.index.directoryreader.open(directory directory, indexdeletionpolicy deletionpolicy, indexcommit commit, boolean readonly, int32 terminfosindexdivisor) +57    lucene.net.search.indexsearcher..ctor(directory path, boolean readonly) +29    examine.luceneengine.providers.lucenesearcher.validatesearcher(boolean forcereopen) +136 

the other (i think related issue) in cms, when opening developer section, javascript alert huge error message in relating lucene

error: {"message":"an error has occurred.","exceptionmessage":"the 'objectcontent`1' type failed serialize response body content type 'application/json; charset=utf-8'.","exceptiontype":"system.invalidoperationexception","stacktrace":null,"innerexception":{"message":"an error has occurred.","exceptionmessage":"could not create index searcher supplied lucene directory","exceptiontype":"system.applicationexception","stacktrace":"   @ examine.luceneengine.providers.lucenesearcher.validatesearcher(boolean forcereopen)\r\n   @ examine.luceneengine.providers.lucenesearcher.getsearcher()\r\n   @ umbraco.web.search.examineextensions.getindexreaderforsearcher(baselucenesearcher searcher)\r\n   @ umbraco.web.search.examineextensions.getindexdocumentcount(luceneindexer indexer)\r\n   @ umbraco.web.webservices.examinemanagementapicontroller.createmodel(baseindexprovider indexer)\r\n   @ system.linq.enumerable.whereselectenumerableiterator`2.movenext()\r\n   @ system.collections.generic.list`1..ctor(ienumerable`1 collection)\r\n   @ system.linq.enumerable.tolist[tsource](ienumerable`1 source)\r\n   @ newtonsoft.json.serialization.jsonarraycontract.createwrapper(object list)\r\n   @ newtonsoft.json.serialization.jsonserializerinternalwriter.serializevalue(jsonwriter writer, object value, jsoncontract valuecontract, jsonproperty member, jsoncontainercontract containercontract, jsonproperty containerproperty)\r\n   @ newtonsoft.json.serialization.jsonserializerinternalwriter.serialize(jsonwriter jsonwriter, object value)\r\n   @ newtonsoft.json.jsonserializer.serializeinternal(jsonwriter jsonwriter, object value)\r\n   @ system.net.http.formatting.jsonmediatypeformatter.<>c__displayclassd.<writetostreamasync>b__c()\r\n   @ system.threading.tasks.taskhelpers.runsynchronously(action action, cancellationtoken token)","innerexception":{"message":"an error has occurred.","exceptionmessage":"read past eof","exceptiontype":"system.io.ioexception","stacktrace":"   @ lucene.net.index.segmentinfos.findsegmentsfile.run(indexcommit commit)\r\n   @ lucene.net.index.directoryreader.open(directory directory, indexdeletionpolicy deletionpolicy, indexcommit commit, boolean readonly, int32 terminfosindexdivisor)\r\n   @ lucene.net.search.indexsearcher..ctor(directory path, boolean readonly)\r\n   @ examine.luceneengine.providers.lucenesearcher.validatesearcher(boolean forcereopen)"}}} 

have tried umbraco forum have had no replies. if it's no-brainer, still need know of course.

any advice appreciated.

i'd indexes (they in app_data\temp\....), , delete them , restart app pool.

umbraco rebuild them (can take 5-10 mins huge database - 150k nodes) on next start up.

it might corrupt index (in case, grab backup , use luke on it, see if broken), or possibly version of index changed - same result.
