Hello, Our web site uses JasperReports library to run some basic reports. We've notice that on some occasions when larger volumes of reports are run our tomcat6 server comes to a grinding halt and requires a restart. After eliminating some other sections of our site as being the issue our next stop was Jasper. I created a load test and profiled a run of 500 reports and immediately noticed that there seemed to be memory leak (see image of surviving generations). Is this a know issue in Jasper? If not; how could my implementation cause a leak? What other information can I provide?
