Oracle BDA: OEL 5.8 Kernel Hang

Following up on my post yesterday about Exalytics having problems of a quite serious nature, today I introduce you to the Oracle Big Data Appliance and how it experiences kernel problems on version 2.4 as well in MOS note 1624337.1 if you are running it on the Oracle Enterprise Linux 5.8 OS.  Symptoms include being unable to ping or ssh servers due to Ethernet interfaces going down or the OS kernel hanging, and in some cases the server actually runs out of memory.  There is a workaround listed, but you can avoid this problem by upgrading to OEL 6 or patching BDA to 2.5 when it is released.
