maximum number of FD events

[Fr34k]

Hello,

Environment:  Solaris10 SPARC and x86, BIND 9.7.3-P3 and 9.8.1

Anomaly:  In our logs, we have been noticing "maximum number of FD events" entries.  For example,
  named[8592]: [ID 873579 daemon.info] sockmgr 288760: maximum number of FD events (64) received

Action:  Our web searches have not found a lot of information on this.  One resource suggested that a few of these are "normal".

We found someone else who seemed to suggest a "fix" by increasing the number of sockets.
We figured we would give that a shot and see what would happen.  We tried 128, and then 256 -- but we still see these messages:
  named[14050]: [ID 873579 daemon.info] sockmgr 288760: maximum number of FD events (128) received
  named[15910]: [ID 873579 daemon.info] sockmgr 288760: maximum number of FD events (256) received

Does anyone have more information, suggestions, comments?

Thank you.
