Hi Aaron,
Thanks for the test.
I see another UVM error without swap when it reboots -
[  93.0939435] UVM: pid 987 (makemandb), uid 0 killed: out of swap
[  18.0222632] UVM: pid 1392 (postconf), uid 0 killed: out of swap
[1]   Killed                  ${POSTCONF} -c ${def_config_directory} -h mult... |
      Done                    sed "s/,/ /"

However, these messages only happen in the booting process.
Everything looks well when I login shell.
