http://issues.apache.org/bugzilla/show_bug.cgi?id=37793 Summary: org.apache.jasper.runtime.BodyContentImpl doesn't reset the 'cb' character array, causes memory leak Product: Tomcat 5 Version: 5.5.9 Platform: PC OS/Version: Windows 2000 Status: NEW Severity: normal Priority: P2 Component: Jasper AssignedTo: tomcat-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] CC: [EMAIL PROTECTED] In the constructor of BodyContentImpl, member variable 'cb' is initialized via cb = new char[bufferSize]; with default buffer size = 512. This character array grows at run time to accommodate the body content. In our case, one of our pages produces body content over 4 mega characters, resulting the 'cb' array to be expanded to over 8 mega characters. The problem is that this huge array never gets reset due to the object pooling implementation in Jasper (JspFactoryImpl maintains a pool of PageContextImpl objects. Each PageContextImpl object maintains an array of BodyContentImpl objects), so the memory it consumed is never returned to the heap. One suggestion is to reset the 'cb' character array in the setWriter() method. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
