Activity_Log deadlock

asked on September 10, 2019

Workflow 10.3.

I am experiencing frequent deadlocks in the dbp.Activity_Search table of my workflow database as new activities are written and deleted during workflow processing.  I have just discovered that this table contains over 2,000,000 million old rows (From 2017).  This is prior to my tenure and I am not sure how they got "stuck" in this table and never deleted.  i believe theses rows are the culprit in my deadlocks.

Can I simply delete these rows without adversely impacting my production workflow server?  If not, how to proceed to clean up this table?

Workflow will retry on deadlocks, the messages are reported as information.

Activity_search is a live table pertaining to running instances. The data will be moved to activity_search_log when the instances complete (then purged once it ages out). Do not delete data from this table.
