Hi,
It looks like i have found the solution:
In my case i was accessing the same (quite large) table subsequetly. (i was extracting table to qvd's and then dropping table after reloading it)
It took a few seconds to store it to qvd and it looks like that sql or. qv needs some time before "re-accessing" the same large table in sql.
Solution:
1 reload of the large table
2. reloading few other tables
3. and then agian reloading the same table.
In my case it works ok now.
P.S. It is funny thougn because this problem appeared all of the sudden (it was working fine for a month but now i got this error)
Cheers,
