file upload string or binary data would be truncated

Hi Guys I have been struggling with this issue for days now. I have a website that uploads different file types, creates thumbs from the files and saves the file and thumbs to their respective folders. every so often it throws an exception string or binary data would be truncated, Ive never encountered this locally. I have a problem pinning down the circumstances that it happens, I thought it was documents with spaces in the name but that works sometimes as w开发者_Go百科ell. This is really bugging me and I need to fix this. The db table fields are long enough, trust me . Has anyone else ever encountered this issue?

Hi I know all this, this is a db error etc, but the fields are long enough. I have not been able to reproduce this, my log files are empty. This is very weird
