STMS buffer not getting refreshed also tp duplicate entries are getting created without target client and when i try to delete it,it goes on running but nothing happens

Dear All,

We are facing the issue in BW production system wherein i am not able to refresh the buffer queue.When i try to refresh it goes in running but nothing happens.

This issue only happens in Production but DEV & QA is fine in the same DOMAIN.

Also duplicate entries are getting created in buffer without target client,when i try to delete it it goes on running but same nothing happens.

I have checked the file system space,stms consistency check,STMS rfc connection,SLOG,ULOG,ALOG everything looks fine.

The only work around is now to import tp from OS level.Any idea on what can be the issue here.

Note:Production is backup controller,DEV is Domain controller.

Thanks & Regards,

Rajdeep
