Re: too many open files, die Zweite
Hallo, Friedemann Schorer [EMAIL PROTECTED]: vs2066134:~# cat /proc/sys/fs/file-max 262144 vs2066134:~# lsof | grep -c / 1411 vs2066134:~# lsof -U | grep -c / 13 vs2066134:~# Soweit nichts besonderes. Die beiden letzten Befehle sind von diversen Fehlermeldungen der Form lsof: no pwd entry for UID 0 begleitet. Da scheint es einen Fehler in deiner /etc/passwd oder /etc/group zu geben. Kann es sein, dass der Eintrag für User/Gruppe 0 (root) fehlt oder korrupt ist? Ich bekomme aber trotzdem ständig Fehler Too many open files ?!? Das geht soweit, daß ich mich teilweise nicht einloggen kann, weil der SSH die PAM-Authorisierung nicht vornehmen kann! Es gibt, wie schon in einer anderen Antwort genannt, auch ein Limit für offene Files pro Prozess. Siehe ulimit -a und /etc/security/limits.conf. Es wäre hilfreich, wenn du herausfinden könntest, welches Prozess diese Fehlermeldung generiert. Steht irgendwas in den Logfiles? Bei der Durchsicht des Outputs von 'lsof' fiel mir auf, daß TLS sehr viele Prozesse offen hat (lsof | grep -c tls ergibt 323) - ist das normal auf einer Box, die einen fast nur privat genutzten SSL-Apache (PHP4), MySQL für localhost, exim4 mit TLS-Unterstützung und FTP nach aussen anbietet? Ja. tls ist kein Prozess, sondern ein Pfadbestandteil zahlreicher Libraries unter /lib/tls/libxxx.so. Jeder Prozess hält während seiner Ausführung zu jeder seiner dynamisch gelinkten Library ein offenes Filehandle.

Hi, before changing anything, i want to know what's wrong. Unmounting my ntfs partitions has no effects (just a try to see).

Each process uses as many file descriptors as it has files open (+ TCP/IP connections, i think - not sure). Typically each file uses a minimum of 3: stdin, stdout and stderr. Plus whatever open files it inherits and opens itself. You can monitor the number of open filehandles through (amongst other things) sar -v - in the sysstat package. HTH -- Karl E.

Re: too many open files
i've recently reinstalled my debian system and i am now getting the following error message: Jan 12 09:00:15 random amd[1162]: setmntent(/etc/mtab, r+): Too many open files any ideas, or pointers to the fm are welcomed. The kernel's out of file handles. Go to /proc/sys/kernel and look at file-max as compared to file-nr as well as inode-max compared to inode-nr. I think nr is the number currently in use... but I could swear I've seen it go higher than max. Anyway, the solution is just to put larger numbers in the max files. In my /etc/init.d, I've got a file called setmaxfiles.sh that contains: echo 4096 /proc/sys/kernel/file-max echo 12288 /proc/sys/kernel/inode-max Then, I made a symlink to it from /etc/rcS.d/S37setmaxfiles.sh so that it will update the kernel structures every time it boots (as it goes through single-user mode). - Joe

Your `ulimit's are too low. Here's what I do, in /etc/profile for
now. (If the user changes shells to non-sh, it won't get run unless,
in the /etc/$shell-init script for that shell, a similar command is
run.) I think this works better than Lshells, or the similar settings
in the `login.defs' file. It will also set ulimits for `sshd' logins.
(sshd has its own internal login, and thus bypasses ulimit settings
for the standard login you'd get with rlogin or telnet.)

Re: too many open files?
Might want to look into the following settings for Apache. # Server-pool size regulation. Rather than making you guess how many # server processes you need, Apache dynamically adapts to the load it # sees --- that is, it tries to maintain enough server processes to # handle the current load, plus a few spare servers to handle transient # load spikes (e.g., multiple simultaneous requests from a single # Netscape browser). # It does this by periodically checking how many servers are waiting # for a request. If there are fewer than MinSpareServers, it creates # a new spare. If there are more than MaxSpareServers, some of the # spares die off. These values are probably OK for most sites --- MinSpareServers 5 MaxSpareServers 10 # Number of servers to start --- should be a reasonable ballpark figure. StartServers 5 # Limit on total number of servers running, i.e., limit on the number # of clients who can simultaneously connect --- if this limit is ever # reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW. # It is intended mainly as a brake to keep a runaway server from taking # Unix with it as it spirals down... MaxClients 150 # MaxRequestsPerChild: the number of requests each child process is # allowed to process before the child dies. # The child will exit so as to avoid problems after prolonged use when # Apache (and maybe the libraries it uses) leak. On most systems, this # isn't really needed, but a few (such as Solaris) do have notable leaks # in the libraries.
