These include 10/10-STABLE/11-Current serving NFS/S= MB and a poudriere build box that is boot on UFS and ZFS for poudriere. Uptimes of 90+ days without issue. It has been a godsend on all machines e= ven my desktop with 8GB full X11 and numerous application + jails. No ZFS tuning. I hope that whatever further review moves forward so this c= an be committed. --mikej -----Original Message----- From: owner-freebsd-fs@freebsd.org [mailto:owner-freebsd-fs@freebsd.org] On= Behalf Of bugzilla-noreply@freebsd.org Sent: Wednesday, August 20, 2014 11:29 AM To: freebsd-fs@freebsd.org Subject: [Bug 187594] [zfs] [patch] ZFS ARC behavior problem and fix https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D187594 --- Comment #23 from karl@denninger.net --- Status -- still grinning, still= doing what it's supposed to on my fairly-heavily loaded production machine= .....
