What kind of app?  Regardless, there are a couple of things that you can 
check I think about it.  You can poke about and see how much of it's 
allocated memory that the JVM is using.  I have seen cases where memory 
leaks slowly burn up the JVM memory and end up requiring a restart. 
Now, I will admit that I don't know the magic commands to check this 
stuff out but you can find it by looking about the web.

The other thing that I have seen that is where threads in WAS slowly get 
consumed by calls to external apps that fail and never return. As the 
number of available threads in WAS diminishes all users will be sharing 
fewer and fewer threads causing client to wait longer to get serviced. 
This, I think, can be seen from messages in the server log files.

The quick fix for both of these is, of course, to stop and start the app 
- but quick fixes are seldom lasting...
