Yes. The Dockerfile of openim-oimws was was authored by myself.

mariadb:10.6
kafka:3.5.1
mongo:6.0.2
redis:7.0.0

openim server image version: release-v3.5
openim chat image version: release-v1.5
openim-admin:toc-base-open-docker.35
oimws git branch :v3.5.1-alpha.8

Additionally, I also added the following information to the linux system：
net.core.somaxconn=65535
net.ipv4.tcp_tw_reuse=1
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_syn_retries = 2
net.ipv4.tcp_fin_timeout = 10
net.ipv4.tcp_max_syn_backlog = 8192
net.ipv4.tcp_fastopen = 3
net.ipv4.tcp_slow_start_after_idle = 0
net.ipv4.tcp_keepalive_time = 60
net.ipv4.tcp_keepalive_probes = 3
net.ipv4.tcp_keepalive_intvl = 6

When I use netstat cmd in linux console:"netstat -nat | grep FIN_WAIT2|wc -l", FIN_WAIT2 TCP connection number is about 28245 now.
