Uptime is the sum of two numbers.  One number is the average number of 
processes in "D" state, the other is the average number of programs that 
are ready to do CPU operations.

"D" state processes are processes that are blocked on disk IO.  It sounds 
like there is a device driver error in your system related to disk IO 
that causes processes to get blocked, and that in this instance 37 
programs have become blocked on disk IO.

I suggest that you run the command "dmesg" and/or check /var/log/kern.log 
for information on what went wrong.

Also please note that we can't help you solve such problems without 
information on what kernel version you run.
