Every probe is an RPC to the vldb and file servers that must be
processed.  There are a limited number of RPCs that can be processed in
parallel.  Increasing the frequency of probes from once every five
minutes to once every 10 seconds will impact the performance of the
servers and the clients that need to send them.
