Build Identifier: 20110218-0911 Hi, I had to say there is huge memory leak in BIRT 2.6.2. I had to return to 2.5.1 version. I tried stress test over my complicated report. This report has 10 tables and 8 charts. Each generating report has different dates so I think it's not cached. I made it under Tomcat with 2GB with queue of max 8 generating reports at the same time. 2.5.1 - ends after avg 35 reports 2.6.2 - ends after avg 20 reports In production server version 2.5.1 is OK. I know there are some known memory leaks (rhino). Reproducible: Always Steps to Reproduce: After some amount of reports garbage collector of Tomcat works for most of the time. This amount depends on complexity of reports, memory for tomcat, reports generated at the same time.
Any script dataset exists in the report?
Yes there are. I have EventAdapters for report and datasets. They are written in Java. I changed only version of BIRT and memory leak appeared.
it had been fixed in 3.7.0RC2
Can you explain what was wrong?
We are using 2.6.2 BIRT and we are very close to the release. It is almost impossible to move to 3.7. If there is a patch for the memory leak for 2.6.2 it will help us a lot. Please anybody comment on this. (I actually tested with 3.7 jars and there is no memory leak there)
This patch only changes one java class: /org.eclipse.birt.report.engine/src/org/eclipse/birt/report/engine/script/internal/DataSetScriptExecutor.java. Please refer to the last version of this class. You can create a patch for 2.6.2 by yourself, and only change this class.
Thanks Gang Liu, it worked for us. What needs to be done to release it as official 2.6.2 patch.
Hi, Short Version: - We need "official" fix for this bug (a plugin jar, 2.6.2.1, or 2.6.3). - This is a show stopper for us (and probably for many other large installations). Long Version: My group is working on a an upgrade to large deployment of BIRT (>100 different templates). We have chosen to upgrade to 2.6.2 for two reasons: (a) This version is bundled with the current IBM RAD 8.0.2, and (b) we expected this to be stable version, addressing many of issues of 2.6.0 and 2.6.1. This bug is a show-stopper for us. We found that we get PermGen after ~200 reports. We could not find any workaround for our server-based reporting. We have just invested large number of hours in testing all reports on 2.6.2. Using other version will require complete retest by multiple teams. I would like to ask for an "official" bug fix for the 2.6.2 version. This can be in the form of "plugin" jar that can be installed on top of 2.6.2, or new version (2.6.3, 2.6.2.1, ...). Having an "official" bug fix will allow us to ask for our vendors and other teams to upgrade. With private, source-level patch - there is no real way to coordinate identical deployment across multiple teams, vendors, etc. In general, production teams will not accept this source-level patch. At minimum, we need a way to download a compiled patch (jar, or similar) from "eclipse.com" or "birt-exchange.com". Also, waiting for 3.7 is unrealistic for us (and I suspect for many clients) - the cost associated with upgrade (testing, coordination, waiting for vendor support) is too big. Thanks for looking into this issue. Yair Lenga

Created attachment 213156 [details] 2nd part
Created attachment 213157 [details] 3rd part Due to the Bugzilla upload file size limitation, please download all the 3 parts of the patch. Then merge them into org.eclipse.birt.report.engine_2.6.2.r262_v20120326.jar. Use this jar to replace the old org.eclipse.birt.report.engine_xxxx.jar in your plugins folder.

I'm running into the same problem - I can't merge the files into one jar
