I am using Python 2.6 on Gentoo Linux and have a routine that gets/puts files to other servers via sftp. We have an ongoing problem with various sftp processes "hanging"; that is, it no longer transfers any data but does not shutdown/timeout. I would like to design a routine that will kick off the sftp (or whatever) module and then monitor it. If the sub-process hangs (or fails any other criteria we define) it could be killed in the main routine and an error could be logged.
How can I do this? I've looked into the subprocess module as well as the Twisted package but I thought that before I launch onto building my own system to accomplish this I'd ask if it's been done before and, if so, how? What are the isues I need to worry about? Thanks, --greg
