My site has been running fine on Lucee 5.3.6 and MSSQL 7.2.2 driver for a while.
I do have one cfc function that isn’t used much at all that does an “exec” on a store procedure and returns a resultset. This will not work on my MSSQL driver datasource but does work find if I use a jTDS datasource to the same database. On MSSQL it shows the exec in debug but 0 records.
The only thing I can think that changed is when I updated to 5.3.6, I created a whole new VM and used the latest installer. So Tomcat 9 instead of 8.5 and JDK 11 instead of 8.
