Working at a client site this week after retuning for a health check I noticed that the SQL Server Log drive for SRS had consumed almost all of the disk available at 30GB!!!
Now as we know the logs for SRS should not be anywhere near that and trying to shrink down the available space proved fruitless as SQL was complaining about the disk being full. The auto grow was configured to consume all disk so this could not be amended easily.
As an Interim measure the recovery model on the database was set to Full which once changed to Simple allowed the database shrink to be implemented and corrected thus preventing SQL from consuming all of the disk.
Now the auto grow can be amended and if required recovery model reverted back to full.
