We've just had a problem with our SQL Server where one of the databases locked up on any data changes. We managed to get everything back up normally by restarting the service.
Afterwards, I started looking at the SQL Server logs, and saw a lot of autogrow events in quick succession on the log file for this particular database (screenshot attached)
What would cause this at such a rate? I always assumed there'd be one autogrow event, which takes a few seconds then it's done (I've not particularly looked for autogrow events before, but I know when it happens, everything seems to just work as normal)
I have checked the disk space on the partition where the log file for this database is, and there is 55Gb of free space
