Hi Chuck, Now I think you must be right.It is not impossible that one of my pages is huge. They are dynamically created, so something could be wrong in my programming to deliver a huge page for some requests.
Isn't there a log of all the requests? I have one running.... Maybe the log could show the size of the responses.... if that is possible, I could see what is the URL of the gigantic page and easily find the reason.... I will check that.... > -----Original Message----- > From: Caldarale, Charles R [mailto:chuck.caldar...@unisys.com] > Sent: Monday, November 15, 2010 10:38 PM > To: Tomcat Users List > Subject: RE: Tomcat 6.0.29 using more and more RAM until it collapses? > > > From: Brian [mailto:bbprefix-m...@yahoo.com] > > Subject: RE: Tomcat 6.0.29 using more and more RAM until it collapses? > > > sometimes Tomcat thinks that needs a huge buffer, so it makes the > > array to increase to millions of chars.
