Symptoms

ILOM firmware 3.2.4 has been very stable due to many ILOM memory leak fixes.

ILOM restarts, or hangs when ILOM firmware revisions above 3.2.4 are installed. The event log will contain the following event for related reboots, but hangs will not:
1656 Sun Jun 11 00:45:44 2017 System Log critical System restarted due to Out-Of-Memory condition.

Cause

1. The T5 & T7 systems contain an ILOM with the Pilot3 hardware. These systems are affected by jumbo network packets prior ILOM version 3.2.8.

2. ILOM firmware 3.2.8 through 3.2.10 contained a bug related to a memory leak in the ILOM's ipmitool interface.

Solution

The jumbo packet problem is resolved in ILOM firmware 3.2.8.

The ipmi problem can be worked around by either periodically resetting the ILOM or by disabling the ILOM's ipmi service.
It is resolved by upgrading to ILOM firmware 4.0 (system firmware 9.8.0 on the T7's or 9.6.20.b on the T5's).
