I take it that you mean that the page can display 5-10k rows of data from a database, rather than the JSP has 10k lines of code in it. I hope so. If not, it's no wonder that the compiler is struggling!! If you do mean DB rows rather than lines of code, I still don't see a particular reason why compiling the JSPs should present such a heavy load if, as you say, you are only changing a few at a time. It sounds more likely to me that it is the processing of the request by the JSPs that is probably eating up the server resources. If compilation is happening in parallel with this, maybe the two together are enough to push the performance off the edge? > -----Original Message----- > From: Vesa Varimo [mailto:[EMAIL PROTECTED] > Sent: Friday 27 May 2005 14:16 > To: Tomcat Users List > Subject: Re: jspServlet runs out of memory while compiling > some jsp files using fork=true > > > > Hmh.. how does you deployment script work?
