memory allocation

[Bennemann]

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:
SHARED_POOL_SIZE=64M
LARGE_POOL_SIZE=32M
SORT_AREA_SIZE=32000000
DB_BLOCK_BUFFERS=121525 (block_size=2048)

Please give a hint.
Thanks

Generally, if you have 600 errors, you'd call Oracle support.

Did you try running the query on the sqlprompt. IF not try that and could you post the status of the issue. Though they say ORA-6000 need to be reported, they aren't that fatel to panic. Lets see what happens when you get to execute the query on the sqlplus. Might be a poor design of query.
