We are using ADO.net appender to write audit records to the a table. Being an Audit table, all the actions performed by the user are recorded to this table along with the User's information like username,account information etc. In production environment we have close to 900-1000 users CONCURRENTLY accessing the system Monday - Sunday. Since every action of each user if tracked to Audit table, we have close to 50,000-200,000 records created every dya in this table.
The problem is, in between, the ADO.Net appender is not writing all the records to the table. It drops a few records and writes the rest. And sometimes(happenned 3-4 times in production), it just stops writing to the table, untill we restart the app servers( IISRESET command). So basically 2 problems.
Currently in PRODUCTION we haven't set reconnectOnError = "true" in the web.config file. We will be setting this in our next PROD build. Will this solve the 2nd Issue(just stops writing to table)?.
We will enable internal debugging in the config file as well in the next PROD build. Will this let us know the exact reason why we are having these issues?
Has this sort of problem been reported earlier?
This is a highly critical issue. If we do not get answers to these quickly we may have to look at other options, which i personally don't want to do.
