We're experiencing a problem with kernel 3.0.93 (SP3).   It seems on servers 
that are memory constrained can go into a loop doing tons of i/o - 8000+ / 
second.
It seems to happen with things like WAS deploys.    We may have also been able 
to recreate use a simple perl array.

Has anyone else seen this?

Yes, we have a high priority SR opened with SUSE.

Oddly we have seen something like this after a kernel update on SP2.  That was 
solved by changing vm.swappiness to something > 0.    We have put it back to 60 
(the default) and still get the problem.
Upping the memory solves it, but obviously, that's not something we want to be 
doing, especially in our constrained dev environment.
