sqlplus & exp "hanging" on a particular table

Hi this is weird.

DB11 is 11.2.0.2 (Oracle Linux)
DB10 is 10.2.0.3 (RHEL)

We want to export a (tiny) schema from DB11 and import into DB10

Using the exp utility on DB10:

$ exp u/p file=/tmp/exp.dmp

Export: Release 10.2.0.4.0 - Production on Tue Oct 11 18:18:02 2011

exported
. . exporting table X_IC_SCREEN_LAYERS 7 rows

.... etc

then it reaches one particular table (6 columns, maybe 300 rows) and just stops dead. No further messages. Lets refer to this as PROBLEM_TABLE. I then executed a couple of specific tests:

$ exp u/p file=/tmp/exp.dmp tables=X_IC_BO_BRANDING

• worked fine

$ exp u/p file=/tmp/exp.dmp tables=PROBLEM_TABLE

• hung as before

"Very strange" thought I.

What about a DB link? Created from the DB10 database to connect to DB11

SQL> create database link db11 connect to .... identified by .... using '....';

OK lets try:

SQL> create X_IC_BO_BRANDING as select * from X_IC_BO_BRANDING_at_db11;

Table created.

SQL> create PROBLEM_TABLE as select * from PROBLEM_TABLE_at_db11; [NOTHING!]

So, quite frustrated and obviously seeing an issue with this table we logged into the corresponding account on DB11 and performed:

SQL> create PROBLEM_TABLE_COPY as select * from PROBLEM_TABLE; Table created.

So PROBLEM_TABLE is acessible and usable in the 11g account - no issues.

Anyone seen anything like this?

PROBLEM_TABLE looks like this:

 ORG_VS_VAL_ID_USAGE_ID                    NOT NULL NUMBER
 ORG_ID                                             NUMBER
 VS_VAL_ID                                          NUMBER
 ORG_ENABLED_FLAG                                   VARCHAR2(1)
 DATE_CREATED                                       DATE
 USER_ID_CREATED                                    NUMBER
 DATE_UPDATED                                       DATE
