I am attaching the full log. (I have removed a few repetitive debug dumps. Due to the large amount of lines processed for this test, header line envelope debug dump lines were too numerous and made the log very large. I have removed them from the attached log.)
I have not had the time to check the cause the yet. But here is the info so that someone may be able to look into this.

```
I am attaching the full log. (I have removed a few repetitive debug dumps. Due to the large amount of lines processed for this test, header line envelope debug dump lines were too numerous and made the log very large. I have removed them from the attached log.)
I have not had the time to check the cause the yet. But here is the info so that someone may be able to look into this ASAP.
Line numbers may be slightly off due to local changes, but the function
nsFolderCompactState::OnDataAvailable(nsIRequest*, nsIInputStream*, unsigned long, unsigned int) (nsMsgFolderCompactor.cpp:716) is hard to miss.
TIA
