Hi

I am running nightly builds, that run the FBCMD.exe. Once in a while I get an exception that makes the build stop.

I have version 5.5.0.589 Installed. Any idea why I get this error?

This is the relevant part in the LogFile:

Hi daphna,   
  
 Judging from the error message: “The process cannot access the file because another process has locked a portion of the file”, I’d be guessing that some background process like a virus scanner may be attempting to scan the log file while it’s being written to.   
  
 If you are running a virus scanner, most of these programs have a way to filter out certain file types. If you had .fbl5 to the “do not scan” list, it will probably prevent this from occurring.   
  
 Regards,
