Hi Hon-Kie,
Thanks for providing the complete entries from lonnet.log for the
"Failed to transfer" messages. That tells me that this message is
being logged by the
removefile() routine in:
/home/httpd/lib/perl/Apache/lontokacc.pm
That routine is called as a PerlCleanupHandler (i.e., at the very end
of handling of a request). The requet itself occurs when a file in
/userfiles/ is requested by an LWP request within the
fetch_user_file_handler() routine in lond. fetch_user_file_handler()
is called to handle a "fetchuserfile" command, which occurs, for
example, when a Course Coordinator creates a new folder in the Course
Editor in a session hosted on the library server.
If you have any recent instances of "Failed to transfer <some file in
userfiles> in your lonnet.log file (without any trailing: 'to host
<home> : <error>') you might look in your Apache log files
(/etc/httpd/logs/ssl_access.log) to see what the return code from
Apache was for the corresponding LWP request.
lontokacc::remove() will log a "Failed to transfer" record in
lonnet.log whenever the request status is other than 200 (OK).
In any event, the failure of lontokacc::remove() to run means that a
file such as:
/home/httpd/html/userfiles/fsu/1c22903f4adf4530afsul/default_1156334647.sequence
on your library server will not have been unlinked, as part of the
cleanup phase.
Note: the corresponding permanent file in:
/home/httpd/lonUsers/fsu/1/c/2/1c22903f4adf4530afsul/userfiles/default_1156334647.sequence
is the one that needs to be preserved. You might check if that file exists.
