As we know, each sbd watcher daemon (servant) is supposed to report 
"healthy" status to sbd inquisitor daemon timely if the object is fine. 
In here, the sbd pcmk servant proactively reported "unhealthy" status.

The "age" value from the log message in this case with pcmk/cluster 
servant is indeed confusing though, since internally there's a coding 
trick for this case to intentionally make any previous "healthy" status 
directly aged (outdated). The value itself here is basically the tv_sec 
value from clock_gettime() minus 1, which is not really meaningful for 
users.
