fixed HTTP page automatically when the # connections for the node is reached
If you say differrent tmm thread work independently. First LB of all those thread should be ws1 all the time (From SOL14358) so it shouldn't LB to any server other than WS1.

Hi Lucas, maybe I expressed myself wrong, and I didn't give correct information, I meant "large get request" the requests are get and not post, so they don't have body, we have a jwt token that by itself occupies 25 Kb, plus other data that adds up and exceeds 32 Kb, unfortunately I didn't find any logs of error in the Big IP.
I have the client error which is this (when http2 is used):
this is a curl that simulates the same size as the get
Failed sending HTTP request: Header overflow
* Failed sending HTTP request
* Connection #0 to host "our.domain.com" left intact
curl: (55) Failed sending HTTP request: Header overflowthe fact is that, unlike the http profile, there isn't parameter for the "Maximum Header Size"
I hope I have explained myself well now, and I hope you have a solution 😀

OK great! Sounds like you have a good method to reproduce the error. Can you share precisely:
- What is the curl command you use to create this behavior
- What is the virtual's HTTP profile configuration? Use "tmsh list ltm virtual <your virtual>" to obtain the profile names, then use "tmsh list ltm profile http <your http profile name>".
In this way, we can run a quick test in a lab to be more sure the solution is correct.
Hi,
you can verify below article as well

The mix up here between header size and content length is puzzling here. When a client POSTs a large file, it's part of the HTTP body which is defined here:
https://www.rfc-editor.org/rfc/rfc9112.html#name-message-body
HTTP Headers are the other part of an HTTP message, and appear before the body.
Do you have any sample content, or sample error messages from /var/log/ltm or /var/log/apm when these requests are unexpectedly denied by big-ip?
