http://bugzilla.opensuse.org/show_bug.cgi?id=1100080 Bug ID: 1100080 Summary: Kontact / /kmail, / akonadi has a memory leak with the standard kernel of leap 15 Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.0 Hardware: x86-64 OS: SUSE Other Status: NEW Severity: Major Priority: P5 - None Component: KDE Applications Assignee: opensuse-kde-bugs@opensuse.org Reporter: stakanov@freenet.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- I experiencing the following: system of 8 GB Ram and 8 GB Swap, SSD Samsung. opening a user with kmail and kpop accounts open, filters active. openning a second user with kmail and imap active leaving now the machine idle (only automatic mail check, with ore w/o a browser open. The, as mentioned in bug 1097605, the machine has: with the 4.4 kernel and this configuration: a memory consumption of 2.5 gb with the original leap 15 kernel: a memory consumption of 6-7 GB of ram and a swap of up to 3.7 gb. All memory seems to be used by the both processes of akonadi, were the akonadi process of the kpop accounts take the most. Closing down kmail will free about 1-1,5 GB of ram. Stopping akonadi will cause a slow freeing up of about an additional 4 GB of ram, however swap will stay on 2GB once created. As said, this is linked to how the kernel 4.12 interacts with the system when idle. This is the case of 100% of sessions, it is sufficient to leave the user open and to let the system idle. If working with the system, the memory will not rise in that way. When recalling the system to life, after being idle, it will then work heavily with the ssd (because it seems it takes the necessary data from swap. The system will be sluggish and will need very long, at times mouse cursor will be frozen (and free after about a minute). Closing down the user with kmail open will eventually free up up to 90% of the claimed memory. When both users are open it may happen that the user instance with imap accounts running will also bloat but only up to 2-3 GB for akonadi, without claiming full 7 GB of ram and 3 of swap. If left alone idle for a period superior to an estimated 3 hours or more, the system will run out of memory, temp will go critical and the system will shut down. All this, I have to point this out will happen only with the combination of standard leap 15 kernel and akonadi/kmail. It does not happen if one uses leap 15 with the 4.4 kernel from 42.3. -- You are receiving this mail because: You are on the CC list for the bug.
