Hello Thomas, or anyone else affected, Accepted landscape-client into cosmic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/landscape- client/18.01-0ubuntu4.2 in a few hours, and then in the -proposed repository. Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users. If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-cosmic to verification-done-cosmic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-cosmic. In either case, without details of your testing we will not be able to proceed. Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping! N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days. ** Changed in: landscape-client (Ubuntu Cosmic) Status: In Progress => Fix Committed ** Tags added: verification-needed verification-needed-cosmic ** Changed in: landscape-client (Ubuntu Bionic) Status: In Progress => Fix Committed ** Tags added: verification-needed-bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685885 Title: Extreme RAM and SWAP usage To manage notifications about this bug go to: https://bugs.launchpad.net/landscape-client/+bug/1685885/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

** Description changed: + [Impact] + + * Memory usage of landscape processes abnormally grows, over time, +even for processes which are generally idle and have no reason to +grow. + + * Most of that memory leak is due to uninitialized python-twisted +logging facilities buffering logs and their context. This fix +Initializes logging with a null handler to have those unused log +entries discarded. + + * Upstream twisted has mitigated part of the issue in recent releases +by reducing the default buffer size. Because of that, the impact +of this bug is greater on xenial. + + [Test Case] + + * register a landscape client and log the memory growth over a day + + * the effect is most noticeable on /usr/bin/landscape-client and less on +the other processes + + * the memory difference on recent releases (bionic and up) is +expected to be smaller (~10mb on bionic instead of 200mb on xenial) + + [Regression Potential] + + * The fix initializes twisted logging, which is unused by landscape +so it is unlikely to have an impact. + + * The fix comes from recommendations on the upstream bug: +https://twistedmatrix.com/trac/ticket/8164 + + [Original description] + This has been noticed on several systems of mine, all 16.04. Landscape Client takes up, over time, an *extreme* amount of system resources. On a 1024MB RAM system, within 3 days to a month, Landscape Client and it's python scripts (possibly cached data?) are consuming massive quantities of memory - in the realm of 512MB RAM and over 400MB of the Swap on the system. This is repeatably shown in other systems of mine as well. Is there a memory leak or something in landscape-client that would contribute to this issue?

[Bug 1685885] Re: Extreme RAM and SWAP usage
I discussed this briefly in #ubuntu-hardened and #ubuntu-server and confirmed that the code hasn't been 'reviewed' lately. I'm setting the importance here to "high" because I just got nipped with this again, and my primary mail server went down because of insanely high swap and RAM usage from Landscape Client. I'm going to test this with a new server to rule out headaches, but if landscape client is going to consume ungodly amounts of RAM, then it should be shelved until the memory leaks are solved. ** Changed in: landscape-client (Ubuntu) Importance: Undecided => High -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685885 Title: Extreme RAM and SWAP usage To manage notifications about this bug go to: https://bugs.launchpad.net/landscape-client/+bug/1685885/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1685885] Re: Extreme RAM and SWAP usage
apport information ** Tags added: apport-collected ** Description changed: This has been noticed on several systems of mine, all 16.04. Landscape Client takes up, over time, an *extreme* amount of system resources. On a 1024MB RAM system, within 3 days to a month, Landscape Client and it's python scripts (possibly cached data?) are consuming massive quantities of memory - in the realm of 512MB RAM and over 400MB of the Swap on the system. This is repeatably shown in other systems of mine as well. Is there a memory leak or something in landscape-client that would contribute to this issue?

Note that the kernel modules listed in the bug may be out of date - I don't have those modules listed, but i hadn't rebooted since they were installed, due to the antivirus in place on this server where I reported from (it's a mail server, so an antivirus engine with amavisd was necessary; note that the usage values for this bug report - for landscape client consuming lots of RAM - had the kernel modules 'off' and disabled with its standard software that correspond with the antivirus engine.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1685885 Title: Extreme RAM and SWAP usage To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/landscape-client/+bug/1685885/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
