Jonas,
When do you see the 18 status flashes? Is it immediately after boot-up, or after your program starts running? What version of software did you upgrade from (6.1.0 or 6.0.3)?
Error 18 is occasionally caused by a problem in the FP-20xx software, but is more frequently caused by problems in the LabVIEW code that is downloaded into the module. One of the more frequent causes is using more RAM through your program than the module physically has.
In the error log you provided, the first several instances of crashes are in the Logos thread. The Logos thread is used for communications over the ethernet. How many computers are linking in to the module at a time? If your program was using up almost all of the free memory, and then another computer trie
d to link to the module, it may not have had the memory to grant the additional subscriptions and then caused the error.
If the primary error is memory usage and you are not using the web server or remote front panels, you can disable the built-in web server to free up more memory for your program.
