Hi Adrian,
The issue is that the client is comming back to the redirector and saying
give me a server that is not in the list of that I have specified in the
"tried=" CGI element. There is no additional tracing information available
(i.e. nothing that print the contents of "tried=". If you have a
reproducible case, then you could turn on client debuggingto see why teh
client doesn't like the servers that the redirector has offered.
Typically, this is due to a "file not found" error or, perhaps, "I/O
error". When you see this happen,
a) issue a locate command for the file in question.
b) Check each server's log for the eror associated with the file (a grep
will do).
This will at least indicate wha is failing at the server level that causes
the client to go back and ask for a different server.
