Hello, i'm running a FreeBSD 11.0-RELEASE vm in AWS EC2 with 3-4 jails on it = and after exactly one week, the vm seems to be freezing, i.e. sshd = resets connections, console frozen, ICMP replies for 1-2 days, then = timeouts) no messages in the logs, no messages on the screen. I tried to reproduce this at home on Xen 4.4 with Linux 4.7 with small = 256M memory VMs and found while running "periodic daily & periodic = weekly": - With file-backed Swap: behaviour like above - With block-backed Swap: behaviour like expected (heavy swapping, = eventual success) - Without Swap: behaviour like expected (killed due oom) - With encrypted block-backed Swap: behaviour like above Is this to be expected?=
