i found quite a few errors of the following form in my server log:
[16/Sep/2002:21:21:09][20313.29329414][-conn482-]
Notice: RP (3357.467 ms): error in rp_handler: serving
GET /tlf/images/Folien-Lektion1.pdf?image_id=24044
ad_url "/tlf/images/Folien-Lektion1.pdf" maps to file "/home/web/tlf-
dev/packages/tlf-kernel/www/images/index.vuh"
errmsg is i/o failed
The .vuh file just contains a call to cr_write_content, to return
uploaded files. It seems as if the script works despite the error. I
am not quite sure what the error message means and how it could
arise. Has anyone else seen this error message?
I am seeing this error quite a bit from heavy use of file-storage. I have not yet looked into the problem. Were you able to discover the source of the problem or a solution?
Yes the problem arises, when the user cancels the download. That causes the socket to close and aolserver cannot write to it anymore. It is nothing to worry about, and i think the error disapeared when i changed db_exec_lob to use ns_returnfile (which is also better because it can handle if-modified-since http commands) instead of ns_writefp.
Thank you for the information, Peter. I also found this discussed here, and it seems the general consensus is that ns_returnfile should be used in place of ns_writefp.
