Error: Tranaction log full due to replication

I had this error in one of the databases and I was trying different possible steps to fix it.

I tried to take a transactional log back up - no luck
I tried to change the recovery model to simple - no luck
The database does not have replication but it does have CDC enabled. So I tried to disable the CDC I got another error related to metadata
I tried to change the db owner to sa - no luck still error
Then the following helped me to get rid of the error that was saying replication

EXEC sp_repldone @xactid = NULL, @xact_sgno = NULL, @numtrans = 0, @time = 0, @reset = 1;

I tried to change the db owner to sa after running the above - success
I tried to disable the CDC - success
I expanded the log file - success

This is how I was able to resolve the issue.

MSDB too large

C drive was growing very fast and then saw that the msdb  data file and log file was huge.

I shrank the msdb log file first.
I ran the following query to see the top higly populated table

SELECT object_name(i.object_id) as objectName,
i.[name] as indexName,
sum(a.total_pages) as totalPages,
sum(a.used_pages) as usedPages,
sum(a.data_pages) as dataPages,
(sum(a.total_pages) * 8) / 1024 as totalSpaceMB,
(sum(a.used_pages) * 8) / 1024 as usedSpaceMB,
(sum(a.data_pages) * 8) / 1024 as dataSpaceMB
FROM sys.indexes i
INNER JOIN sys.partitions p
ON i.object_id = p.object_id
AND i.index_id = p.index_id
INNER JOIN sys.allocation_units a
ON p.partition_id = a.container_id
GROUP BY i.object_id, i.index_id, i.[name]
ORDER BY sum(a.total_pages) DESC, object_name(i.object_id)
GO

Once running the query on MSDB , I found the follwing large tables

I ran the follwing to clear the history

use msdb
GO
exec sp_maintplan_delete_log @oldest_time = '05/12/2017'


This expands the log file so make sure you shrink file


DBCC SHRINKFILE(MSDBLog, 50) --50MB

GO


Then the following maintenance plan was scheduled to run every week.
