[389-users] high-rate queries

[Gerrard Geldenhuis]

Hi Karoly,
You give very little information to go by... it might help to provide log files error and maybe access. Try different loglevels for the error log and explain in a bit more detail what is going wrong with your installation.

Regards

Subject: [389-users] high-rate queries

Hi All,


Is there any reason, workaround for the 389DS about high-rate queries?
Acting as LDAP server for one exim and 5 postfix servers, and for 6 courier-imap servers, libnss-pam

After a time, my clients cannot connect to the 389DS, ldap queries coming back with temporary lookup faulure.
The 389DS has 2 cores with 2GB of ram, related settigns are the following:


# Open file descriptors
*        -        nofile        28192

# sysctl parameters
net.ipv4.tcp_keepalive_time = 120
net.ipv4.tcp_keepalive_intvl = 5
net.ipv4.tcp_keepalive_probes = 2


After I restarting the service, everything is going fine for a while.
OS: Centos 5.5


Any recommendations?
