Yes.. I was able to resolve the problem. the executor was not mentioned which will close the connections/files that are open
Navigate to "jboss-5.1.0.GA/server/ottserver/deploy/jbossweb.sar" and edit server.xml as mentioned below.
Look for following xml snippet.
<Connector port="9090" address="${jboss.bind.address}" maxThreads="250" maxHttpHeaderSize="8192" emptySessionPath="true" protocol="HTTP/1.1" enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="20000" disableUploadTimeout="true" />
Replace this snippet with below one.
<Executor name="appThreadpool" namePrefix="activeThread-" maxThreads="150" minSpareThreads="3" maxIdleTime="30000" />
<Connector executor="appThreadpool" port="9090" address="${jboss.bind.address}" maxThreads="150" maxHttpHeaderSize="8192"
minSpareThreads="3" maxSpareThreads="20" emptySessionPath="true" protocol="HTTP/1.1"
enableLookups="false" redirectPort="8443" acceptCount="100" connectionTimeout="120000" disableUploadTimeout="true" />
Look for following xml snippet.
<Connector port="8009" address="${jboss.bind.address}" protocol="AJP/1.3" emptySessionPath="true" enableLookups="false" redirectPort="8443" />
Replace this snippet with below one.
<Connector executor="appThreadpool" port="8009" address="${jboss.bind.address}" protocol="AJP/1.3" emptySessionPath="true" enableLookups="false" redirectPort="8443" />
hope that helps.
thanks
Kiran
