The size of L2ARC as reported by bfs-stats shrinks over time, and I dont think its an accounting error, as t= he performance of the datbase on the machine returns to what it was when I did= nt have L2ARC at all. The odd thing is, when I reboot the machine, it then shows the L2ARC as bei= ng full of data, and performance goes back to normal. --=20 You are receiving this mail because: You are the assignee for the bug.=
