I don't understand. Z3 and Z12 are completely separated into different folders - no files are shared. Why would there be any waiting? Only 1 Zorro writes to any 1 file...

Re. logs, the diag is not detailed enough - there is no indication at all as to what is hanging or why. Can you provide a list of what API calls are made between the successful login (which is happening) and the printing of the login timestamp (which is not happening)?

Thanks.
