Linux Too Many Open Files In System
I got the following message: tail: inotify cannot be used, reverting to polling: Too many open files Is that a potential problem? How do I diagnose what's responsible for all the open files? I have a list of suspect processes, but if they don't turn out to be the culprits, instructions that don't rely on knowing which process to check would be useful. filesystem share|improve this question asked Aug 28 '12 at 3:07 Andrew Grimm 4192619 1 Have you increased the number errno 24 too many open files linux of file descriptors available via ulimit? –Ignacio Vazquez-Abrams Aug 28 '12 at 3:09 1 @IgnacioVazquez-Abrams That may be helpful to other users, but to me it'd feel like treating the symptom rather than the disease. –Andrew Grimm Aug 28 '12 at 3:13 While you're not wrong, sometimes apps have legitimate reasons for having many files open. –Ignacio Vazquez-Abrams Aug 28 '12 at 3:14 add a comment| 2 Answers 2 active oldest votes up vote 28 down vote accepted You can use lsof to understand who's opening so many files. Usually it's a (web)server that opens so many files, but lsof will surely help you identify the cause. Once you understand who's the bad guy you can kill the process/stop the program raise the ulimit http://posidev.com/blog/2009/06/04/set-ulimit-parameters-on-ubuntu/ If output from lsof is quite huge try redirecting it to a file and then open the file Example (you might have to Ctrl+C the first command) lsof > ~/Desktop/lsof.log cat ~/Desktop/lsof.log | awk '{ print $2 " " $1; }' | sort -rn | uniq -c | sort -rn | head -20 vim ~/Desktop/lsof.log share|improve this answer edited Mar 5 '15 at 8:53 Cookie 295414 answered Aug 28 '12 at 15:13 Andrea Olivato 518613 12 For the lazy: lsof | awk '{ print $2; }' | uniq -c | sort -rn | head –itsadok Nov 27 '12 at 6:10 I got the same error and using ulimit doesn't work.

Although this affects the entire system, it is a fairly common problem. Confluence 2.3 was released and the issue with using too many file handles was resolved via utilisation of compound indexing. To obtain the current maximum number of file descriptors, use 'cat /proc/sys/fs/file-max'. For comparison, an out-the-box ubuntu https://confluence.atlassian.com/display/CONF26/Fix+'Too+many+open+files'+error+on+Linux+by+increasing+filehandles system has file-max set to 205290. Increase Total File Descriptors For System To prevent Confluence from running out of filehandles you need to make sure that there are enough file handles available at the system level, and that the user you are running Confluence as is allowed to use enough file handles: Run the command sysctl -a. If this is less than 200000, increase the number of file handles by editing /etc/sysctl.conf and changing the property fs.file-max to 200000. If there isn't a value set already for this property, you need to add the line fs.file-max=200000. Then run sysctl -p to apply your changes to your system. Increase Total File Descriptors For User Linux also limits the number of files that can be open per login shell. To change this limit for the user that runs the Confluence service you will need to adjust the user limit configuration. For PAM enabled systems For Linux systems running PAM you will need to adjust /etc/security/limits.conf The format of this file is

You can resolve this by increasing the ulimit (this is an operating system setting too many that allows more concurrent files to be open at a given time). Note: This issue potentially affects any version of xMatters running on Linux/Unix. In particular, we have observed this issue in relation to the logging feature that zips log files after x number of files have been created; however, it may affect other features or processes. To resolve this issue: too many open From a bash prompt, check the open file limit by executing the following command: ulimit -a Note the value beside open files. Set the value to 90000 or unlimited: ulimit -n 90000
ulimit -n unlimited Verify the change by executing ulimit -a again and examining the open files value. Note: If you want this change to be permanent, edit your .bashrc file to add a line that executes this command. Update Some customers have encountered the following error message when attempting to execute the ulimit command: -bash: ulimit: open files: cannot modify limit: Operation not permitted If you encounter this error message, you will need to have your system administrator increase the hard limit for nofile. For example: Open the following file in a text editor: /etc/security/limits.conf Modify or edit the hard limit for nofile as follows, where

There are several blogs around the internet that tries to deal with this issue but none of them seemed to do the trick for us. Usually what you do is to set the ulimit to a greater value (it's something like 1024 by default). But in order to make it permanent after reboot the first thing suggested is to update the /proc/sys/fs/file-max file and increase the value then edit the /etc/security/limits.conf and add the following line * - nofile 2048 (see here for more details). But none of this worked for us. We saw that when doing cat /proc/
