Could be, but I am not aware of any problems that would cause UI. The user name and password are ok, the network connection is ok. The current version of the program has been in use for two months, getting run about 400 times a week (3200 runs). The previous version did not use the Oracle server, it read .txt files. Testing of the current version was minimal, as the previous version has been in use for 3 years. I only enabled the "Unattended Server Mode" 2 weeks ago, and I have run into this problem 2 times in the last 800 runs. It is worth noting that we were having Oracle performance problems.

As I am writing this, it happened again, only on this line:

REPORT FORM (XRPTNAM) TO FILE (SUBSTR(STRTRAN(cpFilNam,'.'),1,8)+".RPT") ASCII

Again, there shouldn't be any UI going on.
