I'm running a PHP in container built on unit:php8.2. Here is the Dockerfile I'm using: https://github.com/islamic-network/php/blob/master/8/8.2/Dockerfile.nunit.
Every few seconds I'm seeing the following in my logs:
./src/libmemcached/hosts.cc:268 Assertion "memcached_server_count(ptr) * MEMCACHED_POINTS_PER_SERVER <= MEMCACHED_CONTINUUM_SIZE" failed for function "update_continuum" likely for "invalid size information bein │

Unit limits are set, so each process is killed and a new one comes up after serving 10,000 requests. I suspect this is happening each time 10,000 requests are served because I'm serving between 200 and 400 a second which is why I'm seeing it so often.
There's no connectivity problem between the PHP and memcached containers.
Still investigating, but just thought I'd report this here.
