I am glad to hear that your large financial institution (Bear 
Stearns?) is contributing to the OpenSolaris project. :-)

Today's systems are very complex and may contain many tens of disks. 
Syslog is a bottleneck and often logs to local files, which grow very 
large, and hinder system performance while many log messages are being 
reported.  If syslog is to a remote host, then the network is also 
impacted.

If a device (or several inter-related devices) is/are experiencing 
problems, it seems best to isolate and diagnose it, with one 
intelligent notification rather than spewing hundreds of thousands of 
low-level error messages to a system logger.
