Iguana will not Start

Introduction

Iguana does not does not start up correctly. There are two symptoms: Iguana will not start at all, or it starts but then shuts down (almost) immediately.

There are a couple of common causes:

  • The Iguana service/daemon does not have full read/write access to its working directory
  • Iguana been improperly shut down

Note: On rare occasions it is possible that the Iguana local repository can get get corrupted — see Causes of Iguana local Repository Corruption for advice on how to fix this.

Issue [top]

Iguana will not start, or shuts down very soon after restarting.

Solution [top]

These are solutions for the two most common issues.

Iguana does not have full read/write access to its working directory:

  1. Grant read write permission for the Iguana working directory to the user that runs the Iguana service/daemon
  2. Restart the Iguana service/daemon

Iguana was shut down incorrectly:

  1. If the previous Iguana service/daemon is still running in an “indeterminate” or “zombie” state:
    • This “zombie” process can cause a port conflict when you try to restart.
    • Identify and close the previous (zombie) Iguana instance.
  2. If this does not work then restart the server that Iguana is running on.

Note: To ensure that Iguana is always shutdown correctly, follow the instructions in Gracefully Stopping Iguana Service on Windows and Gracefully stopping Iguana service/daemon on Linux.

These articles also have more detailed information on the problems caused when Iguana is not shut down cleanly.

Prevention [top]

  1. Ensure that Iguana the Iguana service/daemon has read/write access to its working directory.
  2. Ensure that Iguana is always shutdown correctly, see Gracefully Stopping Iguana Service on Windows and Gracefully stopping Iguana service/daemon on Linux.
