https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=228557 --- Comment #4 from Martin Birgmeier <d8zNeCFG@aon.at> --- It seems that with this patch the ARC still grows until the system starts to swap again. "swapoff -a" results in "swapoff: /dev/mirror/swap: Cannot allocate memory" In 11.1 this used to work. Also, using "sysctl vfs.zfs.arc_max=xxxxxxxxxx" to reduce the size of the ARC cache does not seem to free memory (top shows that wired memory remains unchanged). ZFS + swap is very broken under 11.2. -- Martin -- You are receiving this mail because: You are the assignee for the bug.
