[Plugin: W3 Total Cache] Minify Errors

After discovering the minify.log I now have some details on the minify errors I’m getting every 1/2 hour or so. They don’t really shed much light on the problem though. My sites are pretty much identical template wise, so I was expecting the same error to occur but it doesn’t.

Can anyone help me debug please?

Thanks
DS
