Hi Alex,
Thanks for all the details. I will build a new squid image off master/v6 to
check for the memory leak with test traffic.
Regarding the TLS session cache, I will try setting it to 100MB. Are there
any stats exposed from the tls session cache that can be monitored to study
the session cache

Sorry, I do not know the exact answer to your question. One can
certainly build master/v6 from git sources, of course.
The following config knobs were tried and did not make mu
Hi Alex,

Looking for something that includes the patch from the PR to introduce the
ip_bind_address_noport socket option on outbound TCP connections, I dont
see any new builds after Sep 6th.

Hi Alex,
Thanks for all the help from the squid dev group with upstreaming the
enhancement to scale up outbound TCP sessions on Linux with the
IP_BIND_ADDRESS_NO_PORT sockopt flag. Our canary instances have been

Hi Alex,
Thanks for going through several steps to help mitigate src port
exhaustion. We are looking to achieve 400-500% more
concurrent connections if we could :) as there is a significant buffer
