N.B. I only run a single instance of Windows 7 or, on rare occasi= on, Linux Mint, so this might not be appropriate for servers running multiple V= Ms at the same time. # From my sysctl.conf Default vfs.aio.max_aio_procs=3D4 # (32) vfs.aio.aiod_lifetime=3D30000 # (3000) vfs.aio.max_aio_queue=3D8192 # (1024) vfs.aio.max_aio_queue_per_proc=3D1024 # (256) vfs.aio.max_aio_per_proc=3D128 # (32) vfs.aio.max_buf_aio=3D64 # (16)=20 I will shortly reduce these further and see how it goes. This does not preclude the possibility that the modifications to the port c= ould fix this far batter, but I have not had an issue with either kernel memory = or error in the VMs with these adjustments. --=20 You are receiving this mail because: You are the assignee for the bug.=
