Crash Recoveries

This isn't urgent, but I am curious. Oracle 8.1.7, NT4 SP6

I have a daily backup strategy that shuts down the database immediate, restarts the database runs an export, shuts down immediate again, stops the services, runs a full cold backup and then restarts the database.

Until recently I was using ORADIM and getting crash recoveries most days. I switched to SQL*Plus /nolog, connect inernal and scripts as I could find no way with ORADIM to startup restrict and wanted to have DBA only access as an extra protection during the export. I still get the following about once a month.
There is never a problem recovering, but why hasn't it gone down cleanly? Should I be looking for a problem that may be about to manifest itself? Running a search I only find references to shutdown abort or failures to recover.
