If you check backend server then you will below event
Error Event ID: 9002
Transaction log for database 'rtcsdx' is full due to 'LOG_BACKUP'.
Resolution:
In order to resolve this issue you need to make sure the back-end is functioning correctly.
You can run the DBCC SQLPERF (LOGSPACE) query to check the size and current capacity of all transaction logs on the back-end server.
You can truncate the transaction logs that reach maximum capacity by performing a SQL Server backup on them. This reduces the file size of the transaction logs.
Once SQL backup complete, you can see event ID 57001 logged on FE.
 
On SQL server you will see event ID: 18265. 
 

Thank you.
