Hi all, I think I understand, but the question is is there anything we can do about it?
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jean-Eric Cuendet Sent: 22 July 2006 18:22 To: Tapestry users Cc: Tapestry users;Tacos Developers Subject: Re: [Tacos-devel] PermGen space Hi all, This problem is very common with Tapestry applications. This is due to the fact that Tapestry uses cglib to generate classes at runtime. Java uses a separate Heap space called "PermGenSpace" to put meta-data about classes, which is never garbage collected (this is "normal" since normally, classes never change...) but with cglib, classes are generated, which add to the PermGenSpace. And the next time your application is deployed, new classes are generated which add to the PermGenSpace, etc... So it fills and become full. So this problem is common to Java+Tapestry/cglib+deployed webapps. I hope this explaination is clear. Else ask questions. -jec Harvey, David a écrit : > Hello all, > > We've been having occasional problems with PermGen out of space errors > thrown during the execution of our Tapestry application.
