We are seeing something strange each evening with one of our production SQL servers.
To cut a long story short, each night something is growing the size of our TempDB. I have manually sized the temp db to 90Gb. However, each morning when i check it, it is suddenly 150Gb in size.
This is new, normally it would run around 75Gb and had done for months. Nothing has changed with this server in terms of new databases. My thoughts currently is that some bad code has been deployed.
So i guess my question is, how do i interrogate the tempdb to see what has made it grow to this size? All i have found online is related to viewing processes that are happening at the time, however by the time i get to check this server in the morning, no activity is currently happening (the server is in a different time zone so its not being used when i get to it).
