What "memory allocation errors in rtorrent" do you mean? > But if it isn't really using that much memory how come I get > memory allocation errors in rtorrent if there's more memory > avaliable? One week ago was observed problem with write speed on ZFS pool with followi= ng=20 configuration on i386: vm.kmem_size_max=3D"1073741824" vm.kmem_size=3D"1073741824" KVA_PAGES=3D512 Write speed in 8 disks (raidz) is 40 Mb/sec and very choppy.=20 If I change to vm.kmem_size_max=3D"999M", write speed increase in 4 times=20 (160Mb/sec). I think this is bug.=20 What is yours configuration?=20 =2D-=20 ________________ =F3 =D5=D7=C1=D6=C5=CE=C9=C5=CD =EB=CF=D7=D4=D5=CE =F2=D5=D3=CC=C1=CE mailto
