I have been upgrading my hourly cds_report.py code to access the IPMI system and report on sensor warnings and power supply failures. One of the systems I am scanning, h1cdsrfm, has its chassis intrusion sensor triggered (the lid was removed at some point in the past). To clear this warning, at 13:09 I cleared the sensor using the IPMI web interface. This appears to have caused a glitch in the long-range-dolphin IPC channels. We saw IPC errors over EX, EY and CS models (see attachement).

I have DIAG_RESET these transient errors.
