I''ve been trying unsuccessfully for the better part of today to write a worker that can use by ActiveRecord model classes.

Hi, I''m trying to use mongrel 0.3.13 with Rail 1.0 Believe it or not, on OS/X it works well for weeks at a time. On linux I''m getting Input/output errors after anything from a few hours to days, never more than a week. Once they start they don''t stop.

Or is it preferable to authenticate against Active Directory or Kerberos? Thank you
