There are many exceptions thrown in solr.log during shutdown the tomcat

[bensonfungjava]

Hi,

I am new to Alfresco 5.  The alfresco 5 has been installed into our server for a while and it works fine.  However, recently, I found that when I shutdown the tomcat from the alfresco provided console, it will show 'UNABLE TO STOP TOMCAT', but the tomcat sometimes still can stop but sometimes cannot.  And behind the scenes, there is a lot of exception thrown in solr.log as below.  Do anyone know why there are such exceptions thrown during tomcat shutdown.
