Re: [Freeipmi-users] ASROCK MT-C224 + ipmiconsole: [error received]: excess errors received

[Albert Chu]

Hi,

This seems to be an error caused by a simple sequence number issue.
Enough messages from the remote service processor have gotten lost, so
ipmiconsole gives up at some point.  I don't know if your log output
below is showing consecutive
"ipmiconsole_check_outbound_sequence_number" errors, but there is
atleast that one big jump from #398 to #429, indicating lots of lost
messages.

You may wish to check network connections and such for errors, lost
packets, etc.

If you believe this to not be the case, there is atleast 1 other known
situation where I know this to occur.  It occurs when the server is
being rebooted (or some similar to that) and the internal serial UART
chip is rebooted and leads to some communication problems between it and
the internal service processor, suddenly leading to huge jumps in
sequence numbers.  Unfortunately, there is no solution for this other
than to restart.
