https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D219399 --- Comment #88 from Nils Beyer <nbe@renzel.net> --- (In reply to Don Lewis from comment #87) thanks for the modified version; I've tried it. It loads the CPU more, yes,= but there's still at least one core (sometimes two or more) idling around. I do= n't get any segmentation faults within an acceptable time frame (<5 minutes). Please try the version that I've attached https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D184539 I know you've said that you've already tried it - but perhaps there's somet= hing different on my system compiler. Here it segfaults after a maximum of one minute. I believe that the key to these segmentation faults are inner-thread core switches that are prevented by pinning these threads to specific cores. How= far any instruction cache is involved with that, I don't know... TIA --=20 You are receiving this mail because: You are the assignee for the bug.=
