What's the bug exactly?
only 1k of fildescriptors by default. Even if hard limit is 1M (at least for
login)
debian sysvinit script has hack that sets 64k fd limit, systemd unit file
doesn't have this hack.
The design of systemd is to enforce the FD limit.
This is coming from the init 0 level of the design and due to this,
squid cannot "patch" the kernel at runtime like any other process.
The OS and systemd do not give any API to allow a request for"more FD".
I assume that these days it makes sense for a request from the kernel or
systemd to implement such a feature but I don't know if anyone have worked on this.
afaik that process can raise its soft limit up to hard limit level.
squid seems not to do this and debian 11 systemd unit files has no setting
of limit at all.

Subject: filedescriptors on debian/systemd
Hello,
I have encountered Debian bug 934208:
2022/07/28 16:40:53 kid1| With 1024 file descriptors available
2022/07/29 06:50:18 kid1| WARNING! Your cache is running out of filedescriptors
according to the bug report:
"Under systemd the default is not to have any limitation at all."
which seems not to be true, but:
Unfortunately there are still some bugs that needs to be straightened
out upstream for Squid to use the --with-filedescriptors value when
there is *no* specific upper limit provided by the OS.
limits when I log in (ssh or console) are 1024(soft) and 1048576 (hard) and
yet squid starts with 1024 FDs.
I have configured:
# cat /etc/systemd/system/squid.service.d/override.conf
[Service]
LimitNOFILE=65536
and after reloading systemd:
# systemctl daemon-reload
and restart squid it seems to work properly:
2022/08/02 15:52:28 kid1| With 65536 file descriptors available
does anyone encounter this bug?
How do you fix it?
