error could be reproduced by calling pvs periodically:
#!/bin/bash
while :
do
pvs
sleep 1
done
use top command to watch RES memory of lvmetad. After a few minutes,
its RES memory will grow for a few KB. Then stop calling pvs, while
its RES will not decrease.
This is because, when lvmetad make reponse for clent request, it
will malloc new chunk for s->vgid_to_metadata, while actually the
new chunk should be added to the reponse dm_config_tree, or it will
make the chunk list of s->vgid_to_metadata keep growing.
