关于getOutputStream() has already been called for this response的问题

新近开发的OA系统，使用tomcat作为servlet容器。在tomcat的web.xml配置文件中将invoker给打开
了。
本OA系统运行的硬件环境是 sun 480，操作系统是solaris 9。
tomcat中关于内存和线程数的设置是如下：
JAVA_OPTS="-XX:MaxPermSize=256m -Xms1024m -Xmx1024m";export JAVA_OPTS

<Connector port="8080"
maxThreads="800" minSpareThreads="100" maxSpareThreads="800"
enableLookups="false" redirectPort="8443" acceptCount="800"
debug="0" connectionTimeout="20000"
disableUploadTimeout="true" />

运行系统经常出现如下错误：
2005-12-30 19:18:30 StandardWrapperValve[jsp]: Servlet.service() for servlet jsp threw exception
java.lang.IllegalStateException: getOutputStream() has already been called for this response

紧接着就出现线程不组的错误，如下：
2005-12-30 22:23:34 ApplicationDispatcher[/zsjgj] Servlet.service() for servlet jsp threw exception
java.lang.OutOfMemoryError: unable to create new native thread
