ZFS ARC stresses memory. I've found a number of bad RAM chips over the years using ZFS. The OpenZFS upgrade significantly changed how it manages ARC. It's likely that prior to the OpenZFS upgrade your memory wasn't stressed to the point of failure. You can try to mask the problem by reducing your RAM clock rate or or increase one of the other latency settings in your BIOS. However, again, this only masks an already weak RAM chip. Like everything, RAM does age over its lifetime. -- Cheers, Cy Schubert <cy.schub...@cschubert.com> FreeBSD UNIX: <c...@freebsd.org> Web: https://FreeBSD.org NTP: <c...@nwtime.org> Web: https://nwtime.org The need of the many outweighs the greed of the few. _______________________________________________ freebsd-current@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
