SQL SERVER ERRORLOG FILE UTILIZING THE FREE SPACE

I’m stuck up in one of the issue.

I’m Using SQL SERVER 2008 R2.
The SQL SERVER Log file is utilizing the disk space.
When ever I clear the space in the DRIVE, the SQL SERVER Error log file starts to utilize the free space.

Log file path is available in C:Program Files (x86)Microsoft SQL ServerMSSQL10_50. WINCCMSSQLLogsERRORLOG

Kindly, help me to resolve the issue.
