more on ORA 03113: end-of-file on communication channel

I realise there are many postings on this subject but I still can't see the answer (this is local access through svrmgrl not a net config issue).
Here is some more info:

1. System changes noted below
2. The error occurs immediately after switching to the ora8i user and issuing $ svrmgrl Oracle Server Manager Release 3.1.7.0.0 - Production ORA-03113: end-of-file on communication channel
3. If I change my ORACLE_SID to a database that does not exist I do not get the error (immediately) - so what is svrmgrl doing to cause the error - I completely stopped the database instance so there are no processes running for this instance but it still gets the error.
