https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D275594 --- Comment #106 from Olivier Certner <olce@FreeBSD.org> --- Still could not spend much time on it today, tomorrow should be OK. I'll s= tart with D44170. (In reply to Anton Saietskii from comment #102) Yes, 64GB is already plenty. Actually, this is what I have on the machines running poudriere. The main difference to your configuration is that I'm u= sing `USE_TMPFS=3Dno`. Thanks for detailing your reproducer, I'll try something similar and report. (In reply to Mark Millard from comment #104) Seems to be in line with Anton's reporting. I may try with some LLVM, shou= ld be easier (less dependencies). (In reply to karl from comment #105) You're mentioning the ARC thread. Are both your source and object director= ies on ZFS? How much RAM? Are you able to trigger the problem after a fresh b= oot and immediately running buildworld and buildkernel? --=20 You are receiving this mail because: You are the assignee for the bug.=
