200 MB is not large at all, and the notifier should not be the cause for the ACT error. It opens the log as read-only, with file sharing set for read-write so any other process can read and write to the log while the notifier is reading. My logs don't always split either, but that's been happening for a long time for me.

PS: Have you looked at your antivirus/malware software as a possible cause?
