https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233414 --- Comment #9 from Leandro Lupori <leandro.lupori@gmail.com> --- (In reply to Mark Johnston from comment #8) With this new patch I was able to use memguard to guard the '128 Bucket' zo= ne for more than an hour of package building. Unfortunately, later I got this panic: panic: _mtx_lock_sleep: recursed on non-recursive mutex memguard arena @ /usr/src/sys/kern/subr_vmem.c:1184 cpuid =3D 40 time =3D 1544566934 KDB: stack backtrace: 0xe0000001dbb4e250: at .kdb_backtrace+0x5c 0xe0000001dbb4e380: at .vpanic+0x1b4 0xe0000001dbb4e440: at .panic+0x38 0xe0000001dbb4e4d0: at .__mtx_lock_sleep+0x178 0xe0000001dbb4e5c0: at .__mtx_lock_flags+0x160 0xe0000001dbb4e670: at .vmem_xalloc+0x2d0 0xe0000001dbb4e7b0: at .memguard_alloc+0xdc 0xe0000001dbb4e890: at .uma_zalloc_arg+0xe0 0xe0000001dbb4e950: at .uma_zalloc_pcpu_arg+0x178 0xe0000001dbb4e9f0: at .uma_zfree_arg+0x4c4 0xe0000001dbb4eaa0: at .uma_zfree_pcpu_arg+0xc8 0xe0000001dbb4eb30: at .uma_zalloc_arg+0x3c0 0xe0000001dbb4ebf0: at .uma_zalloc_pcpu_arg+0x178 0xe0000001dbb4ec90: at .uma_zalloc_arg+0x5a8 0xe0000001dbb4ed50: at .vmem_size+0x1400 0xe0000001dbb4ee10: at .vmem_xalloc+0x320 0xe0000001dbb4ef50: at .memguard_alloc+0xdc 0xe0000001dbb4f030: at .uma_zalloc_arg+0xe0 0xe0000001dbb4f0f0: at .uma_zalloc_pcpu_arg+0x178 0xe0000001dbb4f190: at .uma_zfree_arg+0x4c4 0xe0000001dbb4f240: at ._fdrop+0xa8 0xe0000001dbb4f2d0: at .closef+0x27c 0xe0000001dbb4f3d0: at .fdsetugidsafety+0x35c 0xe0000001dbb4f480: at .kern_close+0x1e8 0xe0000001dbb4f530: at .sys_close+0x18 0xe0000001dbb4f5b0: at .trap+0x664 0xe0000001dbb4f770: at .powerpc_interrupt+0x290 0xe0000001dbb4f810: user SC trap by 0x104829e8: srr1=3D0x900000000000f032 r1=3D0x3fffffffffff3aa0 cr=3D0x24824042 xer=3D0x20000000 ctr=3D= 0x103b9910 r2=3D0x10671858 KDB: enter: panic --=20 You are receiving this mail because: You are the assignee for the bug.=
