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

Hey Marcio,
You will need to add a systemd service file that extends the current one with more FileDescriptors.
I cannot guide now I do hope to be able to write later.
If anyone is able to help faster go ahead.

Hi,
I implemented a Squid server in version 4.6 on Debian and tested it for about 40 days. However I put it into production today and Internet browsing was extremely slow.
In /var/log/syslog I'm getting the following messages:
Aug 31 11:29:19 srvproxy squid[4041]: WARNING! Your cache is running out of filedescriptors
Aug 31 11:29:35 srvproxy squid[4041]: WARNING! Your cache is running out of filedescriptors
Aug 31 11:29:51 srvproxy squid[4041]: WARNING! Your cache is running out of filedescriptors
I searched the Internet, but I only found very old information and referring files that don't exist on my Squid Server.
The only thing I did was add the following value to the /etc/security/limits.conf file:
*-nofile 65535
however this did not solve.
Does anyone have any idea how I could solve this problem?
Regards,
Márcio Bacci
