For sure, something is holding apache worker threads for a long time or indefinitely. when a request for melodigram.com/melodigram/default/gram/b662a1da-8c2b-11e3-b0dc-1231390a0101 is running: Are you using any third party C extension? Are you calling any external program? Where are the files, that are retrieved by the download function, stored? In the same box, or been retrieved from a remote location? the first thing I would try is using strace utility against an apache worker thread to see were it is sitting.
