Description Vojtech Juranek 2011-11-28 13:44:04 UTC 
Description of problem:
Kernel failed to allocate memory for a process: java: page allocation failure. order:5, mode:0xd0, for details see attached part of /var/log/messages.
Given process was a java process. It used only about 1/3 of the heap memory (not sure, why it needed to allocate more memory, maybe for some native libs) and the memory wasn't freed even after killing this process.

Priority is high as we have to restart the machine (happened on production server which is critical for us). 

Version-Release number of selected component (if applicable):
kernel 2.6.18-274.7.1.el5

How reproducible:
Random

Steps to Reproduce:
Not known
  

Additional info:
IBM System x3550 M3, 2x E5640 CPU, 24GB RAM

The system is out of memory and the application is trying to allocate
more memory. This isn't really a bug.
