Hi,

I am using JBoss_3.2.0-tomcat_4.1.24 with default configuration and PostgreSQL as database.

I have deployed a single Stateful Session bean in EAR file which does a very heavy task as compared to other stateless and entity beans.

But when I send lot of concurrent requests to this statefull session bean, it gives me following error for half of the requests.

01:35:11,103 INFO [STDOUT] ### GetProfilesServ:doService()=>I/O Exception for account_id = testsuraj@max.com ###
01:35:11,109 INFO [STDOUT] Could not activate; failed to restore state; CausedByException is:
/opt/jboss-3.2.1_tomcat-4.1.24/server/default/tmp/sessions/GetProfileBean-dxhvoddr-3/dxhx8ptj-3bx.ser (No such file or directory)

../jboss*/server/default/conf/standardjboss.xml file contains following configuration for standard statefull beans ( I am using "default" configuration of JBoss server )

<cache-policy-conf>
 <min-capacity>50</min-capacity>
 <max-capacity>1000000</max-capacity>
 <remover-period>1800</remover-period>
 <max-bean-life>1800</max-bean-life>
 <overager-period>300</overager-period>
 <max-bean-age>600</max-bean-age>
 <resizer-period>400</resizer-period>
 <max-cache-miss-period>60</max-cache-miss-period>
 <min-cache-miss-period>1</min-cache-miss-period>
 <cache-load-factor>0.75</cache-load-factor>
 </cache-policy-conf>
 </container-cache-conf>
 <container-pool-conf>
 <MaximumSize>100</MaximumSize>
 </container-pool-conf>

Also, ..\jboss*\server\default\deploy\jbossweb-tomcat.sar\META-INF\jboss-service.xml shows following configuration.

<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
 port="8080" minProcessors="3" maxProcessors="10"
 enableLookups="true" acceptCount="10" debug="0"
 connectionTimeout="20000" useURIValidationHack="false" />

Can any one throw some light on it ? How to avoid this error ?

Thanks & Regards,

Suraj
