Hi all,

I am facing a frequent OutOfMemoryError on the Java heap space after just 
a few hits on the application. (The page buffer for a few jsps are of the 
range 4000kb) 

The heap size for the app is 128 MB. 

The server i am using is TC 6.0.24 and tomcat-dbcp for pooling and MS SQL 
server 2005 for database. 

Earlier, I was using TC 4 with mssql pooling(pool.exe) without any issue 
on a 64 MB heap size. 

 The following is the configuration for pooling in my context xml : 

<Resource name="jdbc/sql_2005" 
auth="Container" 
type="javax.sql.DataSource" 
removeAbandoned="true" 
removeAbandonedTimeout="60" 
logAbandoned="true" 
testOnBorrow="true" 
maxActive="100"
maxIdle="15"
maxWait="1000"
username="" 
password="" 
driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver" 
url="jdbc:sqlserver://msSqlServer:1433;databaseName=dbName" 
description="SQL 2005 datasource"></Resource> 

Is this an issue with the server memory management or is there something 
wrong with the configuration,
or any other thing that i am overlooking? Please advise.
