What causes OutOfMemoryError ?

   Hi
 Right now I was using tomcat 5.5.25 and got the exception as shown below:

2007/11/16 21:44:01 org.apache.coyote.http11.Http11Processor process
������: Error processing request

After the exception occur ,any request to  my app1 was refused while other
app deployed on the same tomcat server worked well.
I don't  what  can cause the exception and why other apps can still
work.Help please!
