[Fedora-directory-users] fedora-ds-1.0.3 problem: too many fds open
Hi, I have a new issue with fedora-ds today. The server is running 64-bit Redhat with kernel 2.6.9-1.681_FC3smp. It is used for network authentication and for another purposes, and today in the morning authentication was broken. I have restarted slapd-instance locally on the server, and everything works since that fine. In the logs: there was not records in access log from 08:04 till after restart. In the error log everything these lines repeated again and again, before them previous relates to an event 6 days before this: --- [08/Nov/2006:08:18:01 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:18:01 -0500] - Listening for new connections again [08/Nov/2006:08:18:01 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:18:01 -0500] - Listening for new connections again [08/Nov/2006:08:18:01 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:18:01 -0500] - Listening for new connections again [08/Nov/2006:08:18:01 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:18:01 -0500] - Listening for new connections again [08/Nov/2006:08:18:22 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:18:23 -0500] - Listening for new connections again [08/Nov/2006:08:19:01 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:19:01 -0500] - Listening for new connections again [08/Nov/2006:08:19:03 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:19:03 -0500] - Listening for new connections again [08/Nov/2006:08:19:03 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:19:03 -0500] - Listening for new connections again [08/Nov/2006:08:19:03 -0500] - Not listening for new connections - too many fds open [08/Nov/2006:08:19:03 -0500] - Listening for new connections again [08/Nov/2006:08:19:22 -0500] - Not listening for new connections - too many fds open ... ... --- # sysctl -a |grep fs\.file fs.file-max = 101314 fs.file-nr = 4695 0 101314 and no manually inserted adjustment for ulimit for fedora-ds. Nothing interesting I can find in /var/log/messages. Can anybody help to understand what is happened and prevent this in future? -- With best regards, Sergey

Re: [Fedora-directory-users] fedora-ds-1.0.3 problem: too many fds open
I saw in ds71cli.pdf two parameters which may could help in this case, one is nsslapd-maxdescriptors, and other is nsslapd-conntablesize, but in the example it is called another: "Example: nsslapd-ntconntablesize: 4093" on page 55 of this book. What is the correct name for this second parameter? -- Sergey.

What is the correct name for this second parameternsslapd-conntablesize - this is only for connections nsslapd-maxdescriptors is for all file descriptors used by the slapd process. nsslapd-conntablesize < nsslapd-maxdescriptors> ? >
