Squid running out of filedescriptors on CentOS 7
Solution 1:
The number of file descriptors is set in the systemd unit file. By default this is 16384, as you can see in /usr/lib/systemd/system/squid.service
.
To override this, create a locally overriding /etc/systemd/system/squid.service
which changes the amount of file descriptors. It should look something like this:
.include /usr/lib/systemd/system/squid.service
[Service]
LimitNOFILE=65536
Do not edit the default file /usr/lib/systemd/system/squid.service
, as it will be restored whenever the package is updated. That is why we put it in a local file to override defaults.
After creating this file, tell systemd about it:
systemctl daemon-reload
and then restart squid.
systemctl restart squid
