Hello,

I think generally out of the box the initial size is 256 for the SEI_log files, but max size is pictured below and auto growth is enabled. I suggest setting it back to a smaller size of 256 and keep an eye on the logs moving forward.

You need to make sure you are scheduling regular transaction log backups that will allow you to manage the size of your log files. 

The SEI database does not contain transactional data, this hosts the Central Point - i.e. SEI users, reports, process design. I would set this to Simple recovery rather than Full and schedule a backup of say weekly or daily if you are doing a lot of amendments to SEI. I would then shrink the logfile to a much smaller size say 10% of the database - 70Mb with 25Mb growth. I would also increase the database growth from 1Mb to 50Mb
