MSExchangeIS Mailbox Store Warnings

I am getting quite a few warnings (more info at the bottom of this post) on the active node of our CCR cluster at what appear to be random intervals. After googling it a few different ways I can't seem to find anything of substance that is related. Does anyone know if these are normal in Exchange '07 or what I might need to do about these warnings? Just trying to do due diligence.

Thanks in advance!
