https://bugzilla.suse.com/show_bug.cgi?id=1204380 Bug ID: 1204380 Summary: Swap usage going up until OOM killer kicks in Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.4 Hardware: x86-64 OS: openSUSE Leap 15.4 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs@opensuse.org Reporter: jgross@suse.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- On my laptop running openSUSE Leap 15.4 swap usage keeps growing, until after several days processes are killed by the OOM killer. Swap usage isn't going down significantly even after stopping most use processes. After a reboot the same pattern is shown: swap usage is going up again. After 3 days running, I'm seeing 2.5GB swap used: # free total used free shared buff/cache available Mem: 32476508 28181440 749956 22399648 26361408 4295068 Swap: 33554428 2566144 30988284 # cat /proc/meminfo MemTotal: 32476508 kB MemFree: 764712 kB MemAvailable: 4309652 kB Buffers: 748 kB Cached: 25370992 kB SwapCached: 10000 kB Active: 3887988 kB Inactive: 25143556 kB Active(anon): 1726396 kB Inactive(anon): 24281868 kB Active(file): 2161592 kB Inactive(file): 861688 kB Unevictable: 778528 kB Mlocked: 13880 kB SwapTotal: 33554428 kB SwapFree: 30988284 kB Dirty: 6120 kB Writeback: 0 kB AnonPages: 4375308 kB Mapped: 536888 kB Shmem: 22399772 kB KReclaimable: 989620 kB Slab: 1231732 kB SReclaimable: 989620 kB SUnreclaim: 242112 kB KernelStack: 22832 kB PageTables: 99672 kB NFS_Unstable: 0 kB Bounce: 0 kB WritebackTmp: 0 kB CommitLimit: 49792680 kB Committed_AS: 36645776 kB VmallocTotal: 34359738367 kB VmallocUsed: 67064 kB VmallocChunk: 0 kB Percpu: 7296 kB HardwareCorrupted: 0 kB AnonHugePages: 1413120 kB ShmemHugePages: 0 kB ShmemPmdMapped: 0 kB FileHugePages: 0 kB FilePmdMapped: 0 kB CmaTotal: 0 kB CmaFree: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 2048 kB Hugetlb: 0 kB DirectMap4k: 1328552 kB DirectMap2M: 30789632 kB DirectMap1G: 1048576 kB # uname -a Linux jglap 5.14.21-150400.24.21-default #1 SMP PREEMPT_DYNAMIC Wed Sep 7 06:51:18 UTC 2022 (974d0aa) x86_64 x86_64 x86_64 GNU/Linux # df -k | grep tmpfs devtmpfs 4096 0 4096 0% /dev tmpfs 16238252 11580 16226672 1% /dev/shm tmpfs 6495304 35264 6460040 1% /run tmpfs 4096 0 4096 0% /sys/fs/cgroup tmpfs 3247648 140 3247508 1% /run/user/1000 # ipcs -m ------ Shared Memory Segments -------- key shmid owner perms bytes nattch status 0x00000000 28 gross 600 393216 2 dest 0x00000000 31 gross 600 524288 2 dest 0x00000000 32 gross 600 393216 2 dest 0x00000000 35 gross 600 524288 2 dest 0x00000000 38 gross 600 524288 2 dest 0x00000000 41 gross 600 524288 2 dest Summing up different values of all processes from /proc/<pid>/smaps_rollup show much lower swap usage: Swap: 116900 KB Pss_Shmem: 51861 KB SwapPss: 96114 KB -- You are receiving this mail because: You are on the CC list for the bug.
