PLC fails on Attach Deployment target

itsamb

Hi,
We had a PLC workflow in working condition. From today evening we are facing an issue in PLC, that it stuck at 'Attach Deployment Target'. Attached is the screen shot for the same.
Following is the log that I get in content_center.log

Strange thing is that same behaviour is happening with few other workflow also. They stuck at the same task.
Any pointer is appreciated.

I believe this was posted about before (both by myself and someone else) and answered by Rick (I think it was rick - my apologies if I got that wrong)

Go to the command line of the server, run iwgetwfobj taskid for the current task - and look at the end where the successors are.

Chances are you'll find that one (usually the Success one) has a munged description where a space is missing.

Depending on the order in which their listed (success / failure or failure / success) - you'll probably want to issue the command iwcallback taskid 0 (or 1 depending) - and that will allow your job to continue on its merry way.

This is already registered as defect TS-15899 with H-A-IWOV
