Hello, We are experience the mysterious occurrence of intermediate files created during batch execution disappearing during the same batch execution. We have scoured the application and the environment for indications of deleting we may be instigating unknowingly, but there are no deletes except for those we intend at the end of the batch process. We have traced the beginning of this to the time that we upgraded from 4NT to TCC. I wanted to ask if there was any known instance(s) of TCC removing files as an efficiency measure. Otherwise, is there a limit to how many instances of TCC should be instantiated on a given server before it begins to show unexpected issues. For instance, if we are executing multiple instances of the same batch process, might it be deleting the files from another instance even though each instance is using its own distinct directory structure? Here is our version information: TCC 16.03.55 x64 Windows 2003 [Version 5.2.3790] TCC Build 55 Windows 2003 Build 3790 Service Pack 2 Thank you.
