java.lang.UnknownError

Hi everybody,

I have just come across the very strange error.

OS/400 version is V4R5, JDK 1.2, Native JDBC, journaling (transactions).

A simple query:
Select SSAMJ1 From GEPPARAM Where TABLEX = 'IME' and POSTEX is not null
order by SSAMJ1

...sometimes (~30-50% of all cases) produces the following:

java.lang.UnknownError
com/ibm/db2/jdbc/app/DB2PreparedStatementRuntimeImpl.execute(II)I+40
(DB2PreparedStatementRuntimeImpl.java:387)
com/ibm/db2/jdbc/app/DB2PreparedStatement.execute()Z+28
(DB2PreparedStatement.java:1386)
com/ibm/db2/jdbc/app/DB2PreparedStatement.executeQuery()Ljava/sql/ResultSet;
+12 (DB2PreparedStatement.java:239)

...while sometimes it works exceptionally well.

I just wondering if anybody has ever seen something like this.

Regards,
Timur
