Adv search ERROR: Query execution error for testdoc: [IO_READ_ERROR] An I/O error occurred when read

Hi,

I am in the process of creating a new webtop from our existing one. I copied whole 'webtop' folder under 'webapps' and have a new name 'webtopNew'. I deleted some custom comoponents from the WebtopNew and restarted Tomcat. I logged into new webtop and tried to do Advanced search. I got the following error:

Query execution error for testdoc: [IO_READ_ERROR] An I/O error occurred when reading/apache/Documentum/dfc-dqlhints.xml

I see the content of /apache/Documentum/dfc-dqlhints.xml as follows:

<?xml version='1.0'?><!DOCTYPE RuleSet PUBLIC 'dfc.dqlhints.dtd' 'dfc-dqlhints.dtd'><RuleSet><Rule><DQLHint>ENABLE(RETURN_TOP 10)</DQLHint></Rule></RuleSet>

Note: I also see some errors in catalina.out like:

LocalMap

SEVERE: The web application [/webtop] created a ThreadLocal with key of type [null] (value [com.documentum.fc.client.impl.bof.cache.ClassCacheManager$1@38a838a8]) and a value of type [java.lang.Boolean] (value [false]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.
