is there an option to turn just SQL Errors and warnings on, to be written to disk?

They should be logged by default.

My opinion is, that not FR is ignoring attributes, but SQL is simply not delivering them ... from time to time, possibly by timeouts .... I assume, that FR would recognise it by reporting some timeouts or other errors/warnings, but to get them, I need the debug mode, which is too hard to get written to disk at that transaction rate.

Write it to a ramdisk, and periodically rotate the files. Alan DeKok.
