  His message was neither condescending nor rude.  It simply points out that you're blaming FreeRADIUS, when the real blame lies elsewhere.  I suggest learning how to take feedback without getting offended.

  After all, *you* are the one who asked for help.  You should have entertained the idea that perhaps the problem wasn't FreeRADIUS.

  I *hate* it when people ask questions and get offended at the answers.  It's anti-social, and has no place in polite society.

   suggest dropping the idea that you've been offended, and keeping the conversation technical.  The alternative is for you to keep complaining, which will result in you getting unsubscribed and permanently banned from the list.

  That is what Arran said.

  FreeRADIUS calls Python, which calls your software.  If your software doesn't return execution to FreeRADIUS for 2 days, it's the fault of *your software*.  Go fix it.

  Do python / C debuggers exist?  If so, use them.  Use "strace".  These are all tools which are available to you as an administrator.  There is nothing FreeRADIUS-specific about debugging a program.

  I'll bet dollars to donuts that if you run your Python programs from the shell (not using FreeRADIUS), they'll block for 2 days, too.  Which would indicate that the problem isn't FreeRADIUS.
