◆ peerClearRR()

void peerClearRR ( void  )

Called whenever the round-robin counters need to be reset to a sane state. So far those times are:

  • On startup and reconfigure - to set the counters to sane initial settings.
  • When a CachePeer has revived from dead, to prevent the revived CachePeer being flooded with requests which it has 'missed' during the down period.

◆ peerClearRRStart()

void peerClearRRStart ( void  )

This gets called on startup and restart to kick off the CachePeer round-robin maintenance event. It ensures that no matter how many times its called no more than one event is scheduled.
