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
