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.
Best regards,
Ender

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
