Notes/Domino 6 and 7 Forum : NSD is running... log file

Hello,
On trying to save an close a document, the
client crashes with NSD log file generation.
On debugging I found that the debugger reaches till the end of Querysave event but crashes before QueryClose event starts.
Some excerpts from teh generated log file are below. can anyone help me interpret this? What should I do to continue saving and closing the document as usual...
