 Hi,

we have been happily running an OC4J application (Oracle Application Server Containers for J2EE 10g (10.1.2.0.0)) against a 9.2.0.8 database.

We recently upgraded to 10.2.0.3 with the following patches:

p4898608_10203_GENERIC.zip
p5752399_10203_SOLARIS64.zip
p5755471_10203_SOLARIS64.zip
p5871314_10203_SOLARIS64.zip
p5892355_10203_SOLARIS64.zip
p5746875_10203_GENERIC.zip
p5632264_10203_SOLARIS64.zip
p6646613_10203_SOLARIS64.zip
p6646853_10203_SOLARIS64.zip
p5648872_10203_SOLARIS64.zip

we are now geeting lots of the above ORA-07445 errors and the application becomes unusable. The errors fromt the OC4J application logs are:

java.sql.SQLException: No more data to read from socket
 at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:137)

Howdy, Stranger!
