May I ask, this parameter cannot be increased, this limit refers to where
the limit?Can the system see if it can reach 262140, or is there another
configuration limit in the service?

nsslapd-maxdescriptors: 65536
modifying entry "cn=config"
ldap_modify: Server is unwilling to perform (53)
additional info: nsslapd-maxdescriptors: invalid value "65536",
maximum file descriptors must range from 1 to 8192 (the current process
limit). Server will use a setting of 8192.
According to nsslapd-maxdescriptors [1] description in RHDS Configuration
and
schema reference:
----- 8< -----
The number given here should not be greater than the total number of file
descriptors that the operating system allows the ns-slapd process to use.
This number differs depending on the operating system.
----- >8 -----
On RHEL or fedora, the directory server is started through systemd and you
can change the value LimitNOFILE=<val> as described in
/usr/lib/systemd/system/dirsrv@.service.d/custom.conf:
# To change any of the below values, please use a drop-in file in which
# you can declare overrides according to systemd.unit(5), either of:
# - applying to all instances:
# /etc/systemd/system/dirsrv@.service.d/custom.conf
# - applying to a single instance (overriding the above):
# /etc/systemd/system/dirsrv(a)<instance>.service.d/custom.conf
