Hi, I'm building a Galaxy Cloud implementation, and running into a problem uploading data files > 1 Mbyte, or 1,048,576 bytes. I've started Galaxy Cloudman and a single server, all according to to the Wiki. I can upload fasta format files < 1048756 bytes, and general CSV format peptide files, and indeed junk data files built with variants of " jot -r -c 1030000 a z | rs -g 0 100 >junk ". If I upload files (via the built-in Get Data / Upload Files From Your Computer) that are > than approx 2^20 bytes, the upload just hangs in the History and never completes. These files upload fine to a local Galaxy server, and to Galaxy Main. On the Galaxy local server, they run fine with my custom proteomics code. Ditto on the Cloud galaxy server when the (smaller than 1 Mbtye) files successfully upoad. I can't see anthing useful in the logs, but I'm not sure which logs I should be looking at. I'm just looking at tyhe logs presented on the Cloudman admin page. [image: logs.png] My environment is Mac, OS X 10.6.8. My data files are terminated with /n, but the problem manifests the same with Windows style /r/n files. I'll leave it at that in the hope this is a ridiculously simple probelm and needs no more description ! If not, please let me know the logs I should look at and whatever else I should check.
