18.1 Legacy Series / Update to 18.1 breaks requests

« on: May 08, 2018, 11:10:38 am »

I have an OPNsense Setup where three installations are working together.
Our DNS Record points to all three of these installations so that we have a dns load balancing.
We use HaProxy on OPNsense to proxy the requests to our application servers.

I updated two of these installations from version 17.7.12_1-amd64 to 18.1.7-amd64.
After the update some of our requests start failing.
It is reproducable if i do a lot of requests in parallel to one of the OPNsense installations and it only fails if i send the requests to one of the updated installations.
Some of the requests then start failing with a Status Code of 400 or 502.

The resulting response in the case of an 400 looks like this:

Code: [Select]

<html><body><h1>400 Bad request</h1>
Your browser sent an invalid request.
</body></html>

The resulting response in the case of an 400 looks like this:

Code: [Select]

<html><body><h1>502 Bad Gateway</h1>
The server returned an invalid or incomplete response.
</body></html>

Running the same requests to the not updated OPNsense installation works without any problems.

Is there something in OPNsense 18.1 that changed, that may have produced this problem?
