Error description

Local fix
Problem summary
With the current code, the number of I/Os to the repository disk will increase as more nodes are added to the cluster, when disk ping is used.
Problem conclusion
Modified the disk ping driver to coalesce the reads of the send control blocks into one read. The amount of data read stays about the same as with the current driver, but the number of I/O operations performed is reduced, and stays constant regardless of how many nodes are in the cluster.
Temporary fix
