Reduced the number of new log messages to avoid flooding the log with
warnings. For a shared network we now only log the number of subnets from
which the engine attempted to allocate a lease and the number of subnets
in which no pools were available.
In case of lease allocation failure, the allocation engine now logs:
- which shared network the client belongs to
- which subnet (if not shared network) the client belongs to
- which subnets were tried
- for which subnets there were allocation attempts
- for which subnets there were no allocation attempts
