Hi Surbhi,
Could be many reasons.
If the server logger is set to file please check the below points.
Are you able to see server.log file in filesystem?
Also, did you try to delete the file manually while the server was up?
Run DebugLog service manually and check in IS page if the log is logged or not?

Syed Faraz Ahmed
