Render failed for template: templateFunction is not a function

I'm running NodeBB 1.5.3 on AWS and I keep getting this error in the logs

Render failed for template /edx/app/community/nodebb-platform/build/public/templates/footer.jst:
 TypeError: Render failed for template /edx/app/community/nodebb-platform/build/public/templates/footer.jst:

Can someone please tell me whey this occurs?

This occurs on one of the servers in a load balanced environment where there are 2 servers running. If I increase the server count to 4 then out of those 4, 2 servers are having this exception. Servers in our load balanced environment are using redis for pub/sub, MongoDB as the primary database. Sticky sessions are enabled with stickiness time set to 30 seconds. The servers use the same AMI image.

Run ./nodebb build, restart, and try again.

@PitaJ I've tried rebuilding it multiple times. The error pops up in the logs once the active users reach a high number, around 3000+ in my case.

Oh, you're on an old version of NodeBB. This is fixed in the latest version, you should really try updating. I can't help you otherwise than point you to the commits which fix the issue.

[asamolion]

If you can point me to the commits that would be more than enough. I'm running a heavily customized version of NodeBB so I can't update directly to the latest version.

However, I can push the commits for the fix to my fork.

@asamolion Here are the changes:

https://github.com/NodeBB/NodeBB/pull/6649/files

Just use the latest version of benchpressjs (not 1.2.3)
