We have suddenly started getting this alert from one of our customers
servers

Alert on Server01 at 13/02/2006 12:09:18

The processor is experiencing a low level of idle time. Consistently
low levels of idle time can cause performance problems.

Use Task Manager to view the top processes by CPU. If a service or
less important process appears to be unusual, try stopping and then
restarting it.

Looking at the server console indicates that Firebird is the culprit.
This seems to be happeneing on a daily basis and started about a
month ago. We have also seen other instances of this happening on
other server, but not on such a regular basis. when the problem
occours, the users notice a degreadtion in performance of both the
firebired application and also other applications running on the
server. Any suggestions?

FB version 1.5.1.4481 running on Windows 2003 server.
