Sorry, I'm out of ideas.

>Strtofile gave me sometimes "File is in use by another proccess" sometimes in this scenario. TEXT...ENDTEXT too.
>>Since this a log file, have you considered using Strtofile() instead, to simply append to a text file? I haven't heard about any corruption in a text file.

>>>The rebooting is not caused by the program, it existed long before. I'll usually do it but the contract specifies just that the program should read teh data , save it to FTP and restart by itself when the machine reboots. The harware guys of the customer seems to be happy with the device behavoir and my program performs well, its just that I like to have a log table :)

The production machine is often rebooted or the power is cut (that can't be changed). When that happens, the log dbf becomes corrupt (it is always opened during the program execution and the program is designed to run all the time).
