Couple of days ago I was working on a Linux Heartbeat v2 setup.
Upon inserting an XML snippet into the cib cib-adm started eating memory fast until the oom killer kicked in.
The environment was running a fairly old heartbeat-2.0.8 version so I upgraded to heartbeat-2.1.4-2.1 and there I got a nice warning that my XML sintax wasn't correct.
There was a whitespace in the XML syntax.
<expression attribute="#replicationvalue" id="is_lagged" operation ="gt" ... ><
Removing the whitespace solves the problem, also on the older version. So the problem is already fixed upstream.. but you might run into it anyhow.
