<br>
I'm closely monitoring varnish 5.0 stats. I could fix some issues, but I<br>
am stuck on where sc_rx_timeout is coming from.<br>
<br>
Looking at the documentation, it says "Number of session closes with<br>
Error RX_TIMEOUT (Receive timeout)".<br>
<br>
I do not fully understand this sentence.<br>
- Is this a timeout expressing that varnish does not receive an answer<br>
within a certain time from the backend?<br>
- Do these timeouts happen from time to time and are ok, or is there an<br>
issue on the server (code, params?).<br>
- If parameters, which ones could be candidates to tune?<br>
- Also I have issues with more parameters like sc_req_http10 (please<br>
have a look below) and unsure if they are severe.<br>
<br>
I would be happy if you could point me in some direction.<br>
<br>
Cheers,<br>
Jens<br>
