Hi, I was trying to upload a 43Gb BAM file to Galaxy when I encountered this problem. Please let me know how to fix it. I am new to galaxy and python. I have tried uploading files in other formats and they have worked fine. I have not configured error reporting from the web page. I am using galaxy as a local installation.
