Weblogic 6.1 SP2 hangs up at database command, PATCH needed!

Question

Hello,
I use weblogic 6.1 SP2 on Windows and Solaris
DB-Driver: Oracle Thin Driver for Oracle 9i
Database OP System: Win2000
My application runs fine. After some time (about 15.000 db operations)
at load tests, the weblogic 6.1 server hangs up without an error message
in the logs at a any desired database command.
I use the database pool from weblogic.
The database operations are made with the TX-Datasource.
The main database operation is a call of an oracle stored
procedure.
I suppose, that the weblogic hangs up in a synchronized
block of the pool, but the crash could also have an other reason.
After the crash, the whole instance is dead and must be restarted.
I can reconstruct the crash on windows and solaris.
I always thought, weblogic is reliably?
Is there any patch to fix this problem?
I am very thankful for every help to fix this problem.
Thank you in advance
Markus

Hi,
here is the source code of the the stateless session bean (S1), which
calles the oracle stored procedure.The commit or rollback is done in
the main interface (stateless session bean with user managed
transactions).
java.sql.CallableStatement stmt=null;
java.sql.Connection conn = null;
try {
javax.sql.DataSource ds =
at.one.bmw.system.SystemConfig.getDataSource();
conn=ds.getConnection();
stmt=conn.prepareCall("{call routeChargingRecord(?,?,?,?,?,
int i=1;
stmt.setString(i++,seq_number);
stmt.setInt(i++,custTypeID.intValue());
stmt.setString(i++,msisdn.toString());
stmt.setLong(i++,billing_serviceID.longValue());
stmt.setLong(i++,serviceGroupID.longValue());
stmt.setString(i++,transactionID);
stmt.setInt(i++,typeID.intValue());
stmt.setInt(i++,applicationID.intValue());
stmt.setString(i++,gateway_number);
stmt.setString(i++,smsc_serviceID);
stmt.setString(i++,smsc_tarifID);
stmt.setString(i++,desc);
stmt.setString(i++,beneficiaries);
stmt.setString(i++,attr0);
stmt.setString(i++,attr1);
stmt.setString(i++,attr2);
stmt.setString(i++,attr3);
stmt.setString(i++,deliveryNotes);
int xx=stmt.executeUpdate();
try { stmt.close();  } catch (Exception en) {}
try { conn.close();  } catch (Exception eb) {}
conn=null; stmt=null;
} // end try
catch (Exception e) {
this.sessionContext.setRollbackOnly();
try { stmt.close();  } catch (Exception en) {}
try { conn.close();  } catch (Exception eb) {}
throw new EJBAppException(msg+"\n"+e.getMessage());
} // end catch
Thank you for your help.

Hi Markus,
Can you please post the test code that can demonstrate the hang here.
