      Description

      We have a 3.1.3 installation running against a light production load and are occasionally getting this failed assertion:

      FATAL: HttpSM.cc:890: failed assert `0`

      This causes a corruption of the disk cache every time it occurs, such that whenever the traffic server starts back up, it gets into a crash loop and does this over and over each time it tries to start up:

      The configuration for this setup is pretty minimal, and is mostly a single remap rule that chains together the remap_regex and conf_remap plugins to turn off auth for files ending in a particular extension.

      I will add any appropriate configs, logs, etc as needed to help troubleshoot this.
