FinalReleaseComObject and RCW's

We are currently developing software for WinCE 6.0 on a PXA270
processor. Sometimes on some of our units we see unhandled
exceptions, or low memory warnings, but haven't been able to find
anything obvious. In an attempt to get some more detail I tried
enabling Interop logging and noticed something of interest, and was
hoping someone could shed some light on what exactly it means.

Here is a block of the log that I'm talking about:
