![]() It was classified as a tomcat bug, wasn't it a mistake? indeed tomcat 7 is now trying to resolve memory leaks, but the severe messages are still here and all these unclosed local threads are created by Birt Platform. ![]() This issue has been resolved as "not_eclipse" in last may 2011: bug 339191 They begin to appear as soon as at least one rptdesign has been opened. They occur both with WebBirtViewer and a custom application, even when using a non-static birt engine. This kind of message occur on any tomcat version from 6 to 7.022, and whatever the reports involved. Configurations, dependencies, workloads, and repositories should all be the same in the two environments.When undeploying the 3.7.1 birtViewer application or closing my tomcat server i get tons and tons messages like those below / in file attached. There are many possible causes for patches that fail to install correctly, but being able to compare your test environment against your production environment will make troubleshooting much easier. Also, Red Hat customers are welcome to open a support ticket for assistance in resolving the issue. To investigate those, checking logs such as /var/log/messages, /var/log/secure, and /var/log/audit/audit.log might be helpful, as well as using the command df -h to check disk space. In that case, other possible causes could be a misapplied security setting, low disk space, or maybe incorrect user permissions. Suppose the test and production systems have the expected RPMs and same repositories, but patching is still failing. ![]() If that is the case, you would need to investigate why the systems are seeing different information. If my test and production systems show different information for their upstream repositories, then there is a chance that dependencies might not be met or something else might fail. The key lines here are repo-id, repo-updated, repo-pkgs, and repo-baseurl. Repo-expire : 1 second(s) (last: Wed 07:00:00 PM EST) Repo-name : Red Hat Enterprise Linux 8 for x86_64 - AppStream (RPMs) In the following example, we’ll look at the rhel-8-for-x86_64-appstream-rpms repository used by a client to my Red Hat Satellite server: Repo-id : rhel-8-for-x86_64-appstream-rpms Third, list the repositories in yum with the -v argument so that you can see extra information such as the repodate and the number of packages in the repositories: # yum repolist -v Next, refresh subscription-manager: # subscription-manager refresh You should also check to make sure that the available yum repositories are the same on both systems. You could then compare that against the output collected on your test server in its /tmp/. One essential item to check is the list of the installed RPMs on your test server to compare with the versions in your production server.įor example, on the production server: # rpm -qa -queryformat '%\n'| sort &> /tmp/ ![]() You also need to verify all of the patches were applied in testing and that no patches or errors were accidentally missed. Once you have the error output, you will want to see any differences between your test environment versus what you have in production. Depending on how patching was attempted, you might want to try rerunning the updates, this time with verbose output enabled. This might be simply copying a log file to a separate location, or it could be copying the text displayed on the console screen. If updates fail to install, the first thing to do is capture any output on the console or in the logs. Once you have a test environment where you can verify that a given patch bundle should be installed, you will greatly reduce the chances of issues when installing the updates. If you test the patches on different hardware, with different versions of software, or with different workloads or processes than your production environment, there is no guarantee that the patching test results will reflect what will happen in production. When patching, it’s important first to test the patches in a test environment that matches your production environment.
