Frequent pop up messages while saving


We are on HP SM v9.41 P4 hybrid.

While working on a change request / any request, I make a change on the record, click save. I come back again on the record, try to move around the different tabs, type some text or make any change, suddenly i get a message.

"The record has been modified by <userid> since you loaded it.HP Service Manager has loaded the latest record for you". 

I think there is some background update happening after the save done by the user. How do I figure out the rootcauase.
