Hello Rich, list,
Earlier today we started getting this error in our FDS error log
repeatedly. Obviously connections were being refused at this point. I
had to restart the directory server for the server to function again.
Prior to releasing this box into production I did set the parameters
according to the Installation guide specifications. The output of
"ulimit -n" is 8192. The output of "sysctl -p" is below.(I increased
fs.file-max from 64000)Does anything look off?
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_keepalive_time = 300
fs.file-max = 128000
net.ipv4.ip_local_port_range = 1024 65000
I also changed the setting in the config from
nsslapd-maxdescriptors: 1024 to
nsslapd-maxdescriptors: 8192
Is there a way to tweak these settings so that this will not happen in
the future?
This is a dedicated consumer or read only replica.
Directory size is roughly 20,000 users.
We are running FC9 and FDS 1.1.1-3.
We are lacking in RAM but look to improve on that shortly.
I do see on the web past posts to this list regarding this error, I am
currently looking through them. Is there anyone out there that has
experienced this and gotten past it?
Thanks
James

Is your client using windows OS? is there any posibilities that it could be virus replicating and
distributing it self into networks?
If storing file on domain/networks using FDS for authentication, the frequently authentication
process should cause the "too many fds open".
