Hi,
nsslapd-conntablesize = 1024 - I’ve changed on one server to 2028
nsslapd-reservedescriptors: 64 - I don’t know if increase this value?
currentconnections: 960
opened fd (chnaged conntablesize):
find /proc/23515/fd | wc -l
1043
on bad server:
currentconnections: 958 (bad no errors at this moment)
find /proc/172473/fd|wc -l
1028
It looks like change nsslapd-conntablesize fix my. problems.
Great !
Indeed nsslapd-maxdescriptors is a limitation of the connection table in
case conntablesize is set too high.

Hi,
At startup DS creates a connection table with a fixed size.
The message "setup_pr_read_pds - Not listening for new connections - too many fds
open" means that the number of established connections exhausted the table limit.
What are the values of nsslapd-conntablesize and nsslapd-reservedescriptors ?
How many established connections (logconv on access logs or SRCH cn=monitor) ?
regards
thierry

Hi,
I've upgraded freeipa 4.6.x environment on Fedora 27 to 4.8.4 on fedora 31.
- remove old replica
- install fedora 31
- connect as new replica...
now:
389-ds-base-1.4.2.8-3.fc31.x86_64
freeipa-server-4.8.4-2.fc31.x86_64
after that, I have many errors:
setup_pr_read_pds - Not listening for new connections - too many fds open
It looks like fd limit 1024
I've checked:
nsslapd-maxdescriptors:
ldapsearch -xLLL -b "cn=config" -D 'cn=Directory Manager' -W cn=config
nsslapd-maxdescriptors
Enter LDAP Password:
dn: cn=config
nsslapd-maxdescriptors: 524288

It looks like 1024 is connection limit.
Any idea what I've done wrong?
