Hi suresh , As Stefan Helzle mentioned, it would be a failure from the database side—database in read-only mode, transaction locking, and connection loss. I suspect there might be an issue with the Appian connection pool. Did you check the system logs? Did you find any information in the logs?
HI Abhishek Karumuru thanks for response, this is issue happens in the production, that to its not happening for all all records its happens for only 2 records in the specific data source.
Did you check the data for those two records? Is the data correct? Are there any triggers set up for that database table? Also, please check if any processes are running in the background.
hi Abhishek Karumuru yes for the both records the data is correct.
Can you check with your DB admin once? and get the analysis, is there any foreign key error? i suspect there is some locking issue
