MSDB log file max size reset after SQL Patches

I have encountered this several times already after different Cumulative Updates/Service Packs…

We set fixed maximum size for SQL Server databases and update the max size when required. But after installing Service Pack and Cumulative Updates the maximum size is reset to 2,097,152 MB for the MSDB log file:
max size - msdb log

I am going to submit this issue to the Microsoft Connect (hopefully it still works and active) or check if somebody else had similar issues. As this happens only with one system database and only with one file I would suspect that this is a bug.

This is just something to watch out and remember to review after SQL Server patching if you use fixed maximum files sizes.

About usefulness of trivial tasks

I just wanted to share a story that one of my friends-DBAs shared with me.

So, they have internal DBAs responsible for the part of the environment and remote/external DBAs that look after another part of the environment.
In most cases these two groups do not look after each others environments and their responsibilities do not criss-cross. But my curious friend one day decided to do a little disk cleanup/checkup (from the old backups etc.) and discovered that archive logs for one of the mission critical databases have not been cleaned up for a year. The database was under the external group supervision.
After a short investigation my friend discovered that the database didn’t have backups for a year!

The moral is:
1) Even simple trivial tasks can sometimes help you to discover flows
2) Do not rely on third party contractors even if they have a very good reputation. Make an occasional checks. It wouldn’t heart to add a couple more servers to the monitoring.
