Attachment_fu and mysql

Hi folks,

I’m using attachment_fu to upload mp3 files to amazon s3. The files
are between 1 and 5mb each.

Mostly it works fine, but about 1 in 4 uploads will fail, and once an
upload fails the app responds erratically, returning proxy errors and
slowing down overall.

It’s apache/mongrel, with mysql db. I’m watching the log scroll by as
I upload, and there are no errors thrown.

My only guess so far is that if the upload takes a while between
laptop to server and then server to amazon, mysql is vulnerable in the

Any ideas on tracking this down, or on how to protect the db during a
longish update?

controller code follows

thanks much
