I had a talk with senior person today. And he said they configured Limited file-growth to Unlimited. But at that time they were getting Drive space full alerts. And now they changed to limited growth and getting File group is running out of space alerts. I think as Gail suggested best thing is to setup trace file to check what is running against temp during that time.Thanks all for your input.
I'd bet credits to Navy beans that it will be some query that using a DISTINCT in it to overcome duplicate results in the return. The duplicates are usually caused because of a misunderstanding about the data and people end up doing accidental many-to-many joins (which are formed in TempDB usually as hash tables), which are also known as "accidental Cross-Joins.
