Hi,
I am running a busy magento 2 load balanced web server with 3 back-end
PHP-FPM servers and a shared EFS network filesystem on AWS cloud. There
are lots of concurrent users and everything works fine except the fact
that randomly, from time to time I see the following errors in the error
log:
May 4 15:27:01 app-node php_fpm_error [04-May-2023 15:27:01] WARNING: [pool pool.name] child 135046 said into stderr: ERROR: scoreboard: failed to lock (already locked)May 4 15:27:01 app-node php_fpm_error [04-May-2023 15:27:01] WARNING: [pool pool.name] child 135046 said into stderr: ERROR: status: unable to find or access status shared memory
The PHP version used is 8.1.18 on Ubuntu 22 LTS. The PHP-FPM pool config is below:
[pool.name]
pm.status_path = /status
;listen = 127.0.0.1:5001
listen = /run/php-fpm/pool.sock
listen.owner = wwwuser
listen.group = wwwgroup
listen.mode = 0660
user = wwwuser
group = wwwgroup
listen.backlog = 1024
pm = static
pm.max_children = 12
pm.max_requests = 1000
request_terminate_timeout = 0
rlimit_files = 4096
catch_workers_output = yes
security.limit_extensions = .php .phar
I searched on google and I found absolutely nothing about these 2 errors.
Please help. THanks
