Increase TCP Connections for Plex on Ubuntu
Increase the number of simultaneous connections will help with importing Metadata at a faster rate and resolve issues where plex will run out of connections and Queue them in Memory. This could lead to a lockup of the system.
Check the TPC Connection Limit
The default max is 128 open sockets and can be seen by
sudo sysctl -a | grep somaxconn
Now that we see the limit is so low. We can increase the limit.
sudo nano /etc/sysctl.conf
Add the code below to the bottom to increase the limit.
net.core.somaxconn=65535
Use Ctrl + X to save and now reload the sysctl
sudo sysctl --system
Now the new limit is active and can be verified using the first step
sudo sysctl -a | grep somaxconn
