already 3 days I worry about a problem of being kicked off the database.
I can connect to Oracle 8.1.5 using VB application. But after any SELECT with a GROUP or an ORDER I dont get back an curser and loose connection. The sqlnet.log says "Protocol adater error".
There is also a trace on the server with "internal or fatal error". In addition to this there comes an ORA-00600 and a stack trace. There are words like HEAP SIZE, BUCKET and FREE SPACE with not to large values - thats why I thing there may be a parameter problem with the memory sizes.
The server gots 640MB RAM. Oracle installation:
Please give a hint.
