Problem with JDBC-Type 4 and Linux

I often get an unrepeatable error "Refcursor value is invalid" from my jdbc-driver (Oracle) type 4

The statements are not always the same and I cannot repeat this

error. Most of the times the statements, which are very simple, are working fine, but sometimes I get this error.

The same happens with "java.sql.SQLException: Bigger type length than Maximum".

I already search the knowledge base at metalink.oracle.com, the only thing I found is that others

also have the same problems but I didn't finde a patch or a reason why these error occur.

I'm using Oracle 8.1.7 on Linux RedHat. We are using the O/R-Mapping Tool TopLink.

Does anybody have a solution for this?
