PAM Limits (ulimit -n) causing problems on RedHat 8 Oracle 9

[Eric Reischer]

You might want to check the /proc/sys/fs/file-max value; it has bit me in
the past.  When the kernel hits its file-max limit, it produces an error
message that sounds a lot like the one you mentioned.  Are you sure your
problem is with PAM?
