connection_tcp_get_message

Hi,
I have a serious problem, sometimes my JSPs stop getting rendered while static pages are working fine. I am using Apache 1.3.20 with Tomcat 3.2.2 on Linux Kernel 2.4.2-2 for a production server. When I encountered the problem for the first time I thought that it was the java heap problem so now I am starting Tomcat with JVM parameters 96MB initial heap size and 256MB max size. Things were working fine for a while but it again happened, now I am constantly monitoring my application. My server has 512MB RAM which seems OK for the hosted application. But even with a small load this error happened. My static pages keep getting served properly but JSPs don't get rendered at all and after a restart things get fine again. When I examined the mod_jk.log the following errors appear when the JSPs stopped getting served. Please help me with some solution whereby I don't have to keep monitoring and restarting apache and tomcat whenever such errors occur, I am always restarting apache after a tomcat restart which was mentioned in one of the mailing lists as a possible reason for the problem. Till now I am not even sure if this is a JVM problem or what???
