Also we r using Jboss Connection pooling as : <min-pool-size>5</min-pool-size> <max-pool-size>150</max-pool-size> <idle-timeout-minutes>10</idle-timeout-minutes> <check-valid-connection-sql>select 1</check-valid-connection-sql> Still during Stress testing (10 simultaneous users) getting following errors for 3 executions out of 10: 1) sepa.aff.AFFException: Connection handle has been closed and is unusable at com.ail.sepa.aff.businesslogic.dao.CategoryImpl.findByCategoryId(CategoryImpl.java:801) at com.ail.sepa.aff.businesslogic.command.GetSiteDetails.executeInternal(GetSiteDetails.java:116) at com.ail.sepa.aff.businesslogic.command.AffCommand.execute(AffCommand.java:42) at com.ail.sepa.aff.businesslogic.AffManagerBean.getSiteDetails(AffManagerBean.java:342) at sun.reflect.GeneratedMethodAccessor215.invoke(Unknown Source) 2) org.postgresql.util.PSQLException: This statement has been closed. at org.postgresql.jdbc2.AbstractJdbc2Statement.checkClosed(AbstractJdbc2Statement.java:2390) at org.postgresql.jdbc2.AbstractJdbc2Statement.getMaxRows(AbstractJdbc2Statement.java:521) at org.postgresql.jdbc3.Jdbc3Statement.createResultSet(Jdbc3Statement.java:36) at org.postgresql.jdbc2.AbstractJdbc2Statement$StatementResultHandler.handleResultRows(AbstractJdbc2Statement.java:188) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1270) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:188) at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:430) Thanks in advance [EMAIL PROTECTED] View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3982893#3982893 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3982893 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
