SQL SERVER ERRORLOG FILE UTILIZING THE FREE SPACE
You can close the existing log file by running
sp_cycle_errorlog
Which will create a new empty file
After that just delete the old log files
You should probably look what errors are being logged &amp; try and fix those so the new error log doesn’t fill up so fast
