[support] Merge term not working

[Swapnil Bhartiya]

I am trying to merge some terms but getting this error. Tried both 
modules, Merge Terms and Taxanomy Manager.

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information 
follows. Path: /batch?id=656&op=do StatusText: Service unavailable (with
