Oracle portal import hangs - no errors

Question

I was trying to Import a newly developed page group into production environment from development environment.
Running Script to Create an Export Dump File - no errors from portal or on
backend.
Running Script on Target System - No errors.
Running imported transport set through The Import Manager on target - doesn't
complete. Doesn't show any errors. It runs repeatedly and doesn't import any
objects.
Please note the same transportset imported on Testing without any errors.
### Steps to Reproduce Problem ###
I created a Test page group in development. Exported and ranthe generated script in export mode on the server. Moved the files to target and ran the script in
import mode. Ran the imported transport set through The Import Manager on
target system.
No errors at any stage and it doesn't import and it hangs there.

Hero,
The import log file indicates that import fails for trigger WWSBR_THAT_BRIUD_TRG while merging of items. This is a known issue.
Please look at bug 3228369.
This is due to a data corruption issue on SOURCE instance wherein there are pending entries in thingattributes table for
non-existing subtypeattributes.
Mentioned below are the steps that needs to be carried out:
i) Run the data cleanup script for 9023 (released via bug 3121103) in REPORT mode on source instance.
ii) The output file Data_Validation.txt will indicate whether there are any data corruptions.
iii) If any corruptions are identified then take a database backup, shutdown 902 Midtier and run the cleanup script in RUN mode on
source instance to get rid of such corruptions.
Then
iv) Export the pagegroups from source instance once again.
v) Remove the unsuccessully imported pagegroups from target instance using force_delete script.
vi) And import the new transport sets.
Hope this helps.
Thanks,
Pallav
