Running Exchange 2007 SP2 on 2003 SP2 server with seperate HUB, CAS, and CCR cluster roles. For awhile now we will occasionally experience "Log truncation request to the Information Store using RPC has failed" for one or two of our storage groups. Typically a suspend, update, resume fixes it but the problem will eventually repeat with the same or other databases. It occurs regardless of which node is passive. There are no other issues with the cluster. AV is setup correctly with the correct exclusions. Currently running backupexec 12.5. Any insight on potential issue or how to gather more info would be much appreciated! thanks
