Or this less intrusive fix - restart vdsm on the host with host id 2.

To find the host with host id 2, look for this log on all hosts:

    [vdsm.api] START connectStoragePool(..., hostID=2, ...

This will clear the mailbox with the bad checksum. Once cleared
the SPM will stop complaining about the bad checksum.
