I've run into a totally reproducible freeze in 9.0. There are a number of variables involved, but I'm able to reproduce this freeze 100% of the time. I'm installing very small servers in a Xen HVM virtualization environment. Each instance has 128M memory and 4G of disk space. There is 384M of swap encrypted using geli_swap_flags="-d -l 256 -s 4096". The rest of the disk space is encrypted with "geli init -b -v -a hmac/sha256 -l 256 -s 4096 /dev/ada0p4". After I've installed a VPS in this way, I run the freebsd-update fetch command and it freezes at: Applying patches... I've been trying to diagnose the problem by running top and watching what happens during this stage. I noticed the following: 1) the box runs out of physical memory at this stage (totally expected, that's why there is sufficient swap space). 2) All the processes except 2 sleep: 31 processes: 1 running, 29 sleeping, 1 waiting 3) the box is responsive to hitting enter at the console (it produces another login: prompt) 4) sshd is asleep, so I can't ssh into the box 5) if I try to login to the console, it lets me enter a username then locks up totally, it does not present me with a password: prompt. 6) it has not run out of swap, nowhere close: Mem: 54M Active, 9524K Inact, 41M Wired, 24K Cache, 21M Buf, 32K Free Swap: 384M Total, 6452K Used, 378M Free, 1% Inuse 7) the moment it runs out of physical memory it begins being unresponsive Any idea what might be going on here?
