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

      FATAL: failed assert `0`
      /usr/bin/traffic_server - STACK TRACE:

      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:

      NOTE: Traffic Server received Sig 11: Segmentation fault

      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.
