Subject broken pipe and outof memory error
Date Thu, 12 Sep 2002 05:24:27 GMT

Hello,
Following error occurs when a JSP program accesed by number users, this 
program access information from database though JDBC. Sometime it works 
fine but when the no. of users accessing it increases , the tomcat server crash 
with broken pipe or outofmemory error. We had increased the memory 
also using 
-Xms32m -Xmx256m
But still we are facing the same problem.

Error is as following:
