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

Hi Carles,
You should check how many files are opened on the system and check what
is the maximum number limit of open file for the system.
You should check also what is the user that receive the "too many open
files" error (I suppose root?) and check how many files can be opened
for that specified user (ulimit -n could help).
You could run also lsof to check how many files are opened and what is
opened. Could you consider something program that does not close a
resource on file?
I don't know how works automount but maybe some resource is not umounted?
Hope that helps.
Alessandro.
