It's a bummer. If you can build your own kernel cherry-picking following revisions may help with long-term stability: r218429 - fixes original overflow causing CPU hogging by l2arc feeding thread. It will keep you up and running for longer until you hit another overflow. If I remember correctly, it will hit you around 100-days of uptime. Following changes were done after ZFSv28 import, so they will not apply directly to 8-RELEASE, but the idea applies to ZFSv15 as well. The changes should be easy to backport. r223412 - avoids more early overflows in time routines. r224647 - avoids time overflow in TXG processing. --Artem _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
