the CPU load is falsely detected as "High"
Its correctly detecting the systems load, it's just not "CPU" specific as the message may lead you to believe. It's the referring to the systems load average, which in your snippet is 2700+. So it is correctly complaining.

Query2: The crmd logs are flooding the pacemaker.log. Any suggestions on how to deal with it?
Rather than mask the issue I would recommend investigating what's causing the high load average (load average is not based solely on CPU utilization). With all of the processes sleeping and the load that high I would suspect something is stuck waiting on a lock. How many of those 11,054 (wow) processes are in a uninterruptible state?
