Scripting cross contamination?

We are calling WinSCP scripts to send files out to multiple ftp servers. (Winscp /script = <script> /ini= <.ini file> /log= <logfl>).

Sometimes when multiple instances of WinSCP executes at the same time, we have found the one instance will pick up the script from the other instance. This causes ftp/sftp failures or files being routed to the wrong destination.

Is this a know issue? Is there anyway to insure this does not happen?

Note: we do use the same .ini file in every script.

Thanks

Can you give me more details on what "one instance will pick up the script from the other instance" actually means? Also what version of WinSCP are you using?

Sorry for the slow response. We call WinSCP scripts from a third party scripting tool using the command line. The ftp scripts are copied from a ftp script folder and things like username, passwords, etc are added to the script file. Then WinSCP is executed via command line redirecting input and output. Sometimes, If multiple WinSCP processes execute at the same time, WinSCP can grab the wrong script from the secondary instance and execute it.

Since this data is healthcare related, we are running into potential HIPAA issues.
