Introduction
One of the nice features of Hugo is the live reload feature. When running Hugo locally, this automatically reloads the page when you make changes to the content or the theme. It means I get instant feedback for the changes I am making. However, I have run into an issue from time to time where Hugo’s live reload feature keeps reloading the page:

100 reloads! You can see from the timings that it is pretty much constantly reloading. This isn’t ideal as it is constantly refreshing the page. There are some discussions on it online, and I couldn’t quite put my finger on what was causing it. With a bit of deducing, it was quite obvious in the end!
Read the message
The first thing of note is the message Asset changed /watching/hugo_stats.json. Opening the file, I could see that it was updating right in front of my eyes. At one moment it read (first 8 lines for brevity):
{
"htmlElements": {
"tags": [
"a",
"article",
"b",
"blockquote",
"body",
And the next it read:
{
"htmlElements": {
"tags": [
"a",
"article",
"artifactreference",
"b",
"blockquote",
Note that the artifactreference tag has been added. I can at least confirm that the file is indeed being updated, but it’s not being done by me! After realising the cause, this is a real give away in hindsight.
Multiple Hugo instances running
Killing vscode fixed the issue, not really a fix is it? But on reopening vscode, I realised my mistake since it reopened all my windows and I realised that I had at some point managed to fire up hugo twice in two command line sessions in separate windows. This results in the hugo stats file being refreshed by the first sesson, which is then detected by the second session, causing a reload, which then rebuilds the file causing the first session to detect a change, and so on ad infinitum.
Wrapping Up
So simple in the end, there are a few discussions about possibile issues in the online help but none of them consider pebkac! I hope this helps someone else out there.
