      Hello,
      This program crashes after 12-24 hours of running. My OS is Ubuntu 11.10, I'm using Python 2.7.2, and gcc 4.6.1.

      Here's the error:

      Looks like you should report this to Psyco, no?

      Also, you can read this on the project's main page:
      """
      16 July 2010

      Python 2.7 is unsupported so far. Anyone interested in porting Psyco to it is welcome. I started the work in a branch but it needs finishing.

      I'll try Python 2.6, but this says 2.7 is supported: http://initd.org/psycopg/features/

      Thanks for the suggestion!

      I'll try Python 2.6, but this says 2.7 is supported

      (OOps, mixed up psyco and psycopg).
      Anyway, if you look at the backtrace, you'll see it segfaults inside psycopg.
      You should report this crash to this project.
      Closing.
