Autofs: too many open files issue
by Carles Acosta Silva 30 May '25

30 May '25

Hi, We are running AlmaLinux 9.3 on several nodes that normally use autofs to mount different kinds of remote directories. Since the last week, we are seeing these errors: automount[2150866]: open_pipe:161: failed to open pipe: Too many open files And automount stops working. It does not seem that any user has arrived at the maximum number of open files. Do you have any idea where we can look to find a solution? Thank you in advance. Best regards, Carles

Those instructions are often from people who really don't understand what they are doing. Step 2 messes everything totally up.

As the error says: your tftp-server.socket is broken. Which probably comes because of step 2 above. # systemctl cat tftp-server.socket will show the content of the active configuration. > May 20 08:27:28 VMWare.lsi.com <http://VMWare.lsi.com> systemd[1]: tftp- > server.service: Got no socket. > May 20 08:27:28 VMWare.lsi.com <http://VMWare.lsi.com> systemd[1]: tftp- > server.service: Failed to run 'start' task: Invalid argument > May 20 08:27:28 VMWare.lsi.com <http://VMWare.lsi.com> systemd[1]: tftp- > server.service: Failed with result 'resources'. > May 20 08:27:28 VMWare.lsi.com <http://VMWare.lsi.com> systemd[1]: > Failed to start Tftp Server. > > > this is my file after removing start arguments: > more tftp-server.service > [Unit] > Description=Tftp Server > Requires=tftp-server.socket > Documentation=man:in.tftpd > > [Service] > ExecStart=/usr/sbin/in.tftpd /tftpboot > StandardInput=socket > > [Install] > WantedBy=multi-user.target > Also=tftp-server.socket > > STill does not start. Yes. Changing that file doesn't make sense either. The tftp-server.socket unit is broken. > What are the correct steps for setting up TFTP . The correct steps are fairly simple: # dnf -y install tftp-server # systemctl enable --now tftp.socket That's all what is necessary to get it running. After it's running, make necessary changes if you need something different. But that's done via the standard systemd overrides and not by putting different files with different names into /etc/systemd/system... I would recommend in your current setup to remove those copied files # /bin/rm /etc/systemd/system/tftp-server.service # /bin/rm /etc/systemd/system/tftp-server.socket # systemctl daemon-reload # systemctl enable --now tftp.socket And then check if you can access it... -Gerald

Re: Virtualbox fail with new almalinux kernel

Following up on this, using rmmod to unload the kvm and kvm_intel kernel modules allows VirtualBox to load my virtual machines, but that still begs the question "why did this happen?" Looking at the .config files for the current and older kernels I have on my almalinux machine (5.14.0-503.38.1.el9_5.x86_64, 5.14.0-503.40.1.el9_5.x86_64, and 5.14.0-570.12.1.el9_6.x86_64), I see that CONFIG_X86_VMX_FEATURE_NAMES=y and CONFIG_VMXNET3=m are set in all of them, so why does it fail with VirtualBox only in the latest kernel? And does almalinux support a module blacklist in /etc/modprobe.d to prevent the kvm modules from loading in future reboots? -- -John (JohnDThompson(a)gmail.com) Appleton, WI USA
