Problem of Internal Server Error

[Per0x]

Hello,

I have a recurring issue with NodeBB 1.9.3 running in docker with redis 3.0.6.
Sometimes the web interface stated "Internal server error" only and I have no access to my forum.
The only solution to remove the issue is to reboot the container.

Here's what the logs show me:

If anyone knows about this problem, thanks for the help.

I have the same if the forum has no traffic for some time. Something inside Node.js timeouts. My fix was to load the forum every x minutes which I do as part of server monitoring anyways. Since then its 100% fine.

@pummelchen Thanks for the response.
Ok for the solution, but If that's true, it's still strange behavior. My forum is in a test period so indeed it doesn't have much traffic, but I come by at least once a day to see just how frequent the error is. It means that if we go on vacation and nobody visits our forum for a few days, when we get back all the owners of a forum under nodeBB have chances to see this error? That's annoying.
