log is showing - kernel: (da0:mpt0:0:0:0): Queue Full

[eculp at bafirst.com]

I have a log with a lot of these messages.  I have no idea what the 
messages mean.  This is a Dell 2850 IIRC, colocated in another country. 
  Is this as bad as it sounds and is there a kernel configuration 
setting that would solve this?

The server is running up to date current.  I know, but it is too late 
to change it.  It was a test machine that was substituted for a broken 
server in an emergency situation and has been there ever since.

Would a remote downgrade to Releng 6 be recommendable.  If so just how 
dangerous would that be.  I can visualize installing it over what is 
there and then rebuilding everything but I'm a bit worried that it 
wouldn't reboot.  If not I will need to weather the storms until the 
7.0 release.  If it weren't so far away I wouldn't worry.

Thanks for any help or suggestions,
