RILOE error

[nicatnite303]

Hello-
We are receiving alerts from SIM from various RILOE's in our org. The alerts are only coming from servers that have RILOE's, not the ones that use the ILO's. The alerts are as follows:
SERVERNAME
CIM:RILO:Interface_Error The host OS has detected an error in the RILO interface. The firmware is not responding.

The RILOE is accessible, and the server is unaffected as well. Nothing in the event logs seems to indicate what might happen right before the error is generated and we have reset the RILOE on certain servers to see if that clears the errors. it is inconsistent as to whether resetting the RILOE has any long term effect. The RILOE firmware is v2.53, and all agents are up to date from what I can tell. I am just curious if anyone has seen this before, or heard of this issue. It's not causing anything but "false alarm" alerts, but it'd be nice to lose those alerts if we could.
Thanks,
Nick

Additionally-
Anyone know if there is a difference between the RILOE Firmware revision of 2.53 from 2/2004 and the 2.53a dated 3/2004 available now as a most recent version?

Our RILOE's are running 2.53 dated 2/2004

Thanks...
Nick
