The problem symptoms are as follows:
1. On BDA V4.2, X4-2 HW, OS OL 6.6, with ILOM version: Version 3.1.2.32 Copyright (c) 2006, 2013, the following ILOM "Temperature", "Fan Speed" and "Other" Warnings are periodically raised like:

2. Searching for hwmgmtd in /var/log/messages also shows lots of related errors like:
