we have a Livecycle ES4 turnkey installation on Winows Server 2008.
Sometimes documents in watched folder are correctly copied to stage subfolder, but then the process get in troubles with errors like this:
com.adobe.idp.DocumentError: java.io.FileNotFoundException: C:\aWatchedFolder\stage\Wxfd67473f1c8ad40cc552e8f9\03_0102.XML (The process cannot access the file because it is being used by another process)
We have checked folder permissions, they are OK; the problem occurs randomly, for example we create 40 XML in a watched folder, 37 are processed, and 3 hangs. If you copy the 3 hanged XML in the input subfolder again, they are processed correctly. We have tried to set up the watched folder so that it processes only 1 file sinchronously; the problems seems to reduce, but sometimes appears again.
