https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D231296 --- Comment #23 from Josh Gitlin <jgitlin+freebsd@goboomtown.com> --- We experienced the kmem_back issues as well, and we're running a Skylake: Intel=C2=AE Xeon=C2=AE Bronze 3106 Processor We haven't seen the issue since reducing ARC size, but the same config had = been stable for years prior to that. (We did change hardware however) Backtrace was:=20 trap number =3D 12 panic: page fault cpuid =3D 6 KDB: stack backtrace: #0 0xffffffff80b3d567 at kdb_backtrace+0x67 #1 0xffffffff80af6b07 at vpanic+0x177 #2 0xffffffff80af6983 at panic+0x43 #3 0xffffffff80f77fcf at trap_fatal+0x35f #4 0xffffffff80f78029 at trap_pfault+0x49 #5 0xffffffff80f777f7 at trap+0x2c7 #6 0xffffffff80f57dac at calltrap+0x8 #7 0xffffffff80dee7e2 at kmem_back+0xf2 #8 0xffffffff80dee6c0 at kmem_malloc+0x60 #9 0xffffffff80de6172 at keg_alloc_slab+0xe2 #10 0xffffffff80de8b7e at keg_fetch_slab+0x14e #11 0xffffffff80de8364 at zone_fetch_slab+0x64 #12 0xffffffff80de848f at zone_import+0x3f #13 0xffffffff80de4b99 at uma_zalloc_arg+0x3d9 #14 0xffffffff826e6ab2 at zio_write_compress+0x1e2 #15 0xffffffff826e574c at zio_execute+0xac #16 0xffffffff80bled74 at taskqueue_run_locked+0x154 #17 0xffffffff80b4fed8 at taskqueue_thread_loop+0x98 Uptime: 18d18h31m6s mpr0: Sending StopUnit: path (xpt0:mpr0:0:10:ffffffff): handle 10=20 mpr0: Incrementing SSU count mpr0: Sending StopUnit: path (xpt0:mpr0:0:13:ffffffff): handle 13=20 mpr0: Incrementing SSU count mpr0: Sending StopUnit: path Ixpt0:mpr0:0:16:ffffffff): handle 16=20 mpr0: Incrementing SSU count --=20 You are receiving this mail because: You are the assignee for the bug.=
