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 an

hitting max open file limit allowed by linux. You need to increase open file limit as too many open files in system centos below: Increase limit Per-User Limit Open file: /etc/security/limits.conf Paste following towards end: * hard nofile 500000 * soft nofile 500000 root hard nofile 500000 root soft http://askubuntu.com/questions/181215/too-many-open-files-how-to-find-the-culprit nofile 500000 500000 is fair number. I am not sure what is max limit but 999999 (Six-9) worked for me once as far as I remember. Once you save file, you may need to logout and login again. pam-limits I read at many places that an extra step is neede for limit https://easyengine.io/tutorials/linux/increase-open-files-limit/ to change for daemon processes. I did not need following yet, but if above changes are not working for you, you may give this a try. Open /etc/pam.d/common-session Add following line: session required pam_limits.so System-Wide Limit Set this higher than user-limit set above. Open /etc/sysctl.conf Add following: fs.file-max = 2097152 Run: sysctl -p Above will increase "total" number of files that can remain open system-wide. Verify New Limits Use following command to see max limit of file descriptors: cat /proc/sys/fs/file-max Hard Limit ulimit -Hn Soft Limit ulimit -Sn if you are logged in as root: Check limit for other user Just replace www-data by linux username you wish to check limits for: su - www-data -c 'ulimit -aHS' -s '/bin/bash' Check limits of a running process: Find process-id (PID): ps aux | grep process-name Suppose, XXX is PID, then run following commands to check limits: cat /proc/XXX/limits Share this:FacebookTwitterGoogleRedditPocketEmailPrint Table of Contents EasyEngineInstall Community Support (Free) Documen

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 system has file-max set to 205290. Increase Total File Descriptors For System To prevent Confluence from running too many open 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
16, 2015 in BASH Shell, CentOS, Debian / Ubuntu, File system, Linux, RedHat and Friends, Suse, Ubuntu LinuxHow do I increase the maximum number of open files under CentOS Linux? How do I open more file descriptors under Linux? The ulimit command provides control over the resources available to the shell and/or to processes started by it, on systems that allow such control. The maximum number of open file descriptors displayed with following command (login as the root user).
Command To List Number Of Open File DescriptorsUse the following command command to display maximum number of open file descriptors: cat /proc/sys/fs/file-max Output:7500075000 files normal user can have open in single login session. To see the hard and soft values, issue the command as follows: # ulimit -Hn# ulimit -Sn To see the hard and soft values for httpd or oracle user, issue the command as follows: # su - username In this example, su to oracle user, enter: # su - oracle
$ ulimit -Hn
$ ulimit -SnSystem-wide File Descriptors (FD) LimitsThe number of concurrently open file descriptors throughout the system can be changed via /etc/sysctl.conf file under Linux operating systems.The Number Of Maximum Files Was Reached, How Do I Fix This Problem?Many application such as Oracle database or Apache web server needs this range quite higher. So you can increase the maximum number of open files by setting a new value in kernel variable /proc/sys/fs/file-max as follows (login as the root): # sysctl -w fs.file-max=100000 Above command forces the limit to 100000 files. You need to edit /etc/sysctl.conf file and put following line so that after reboot the setting will remain as it is: # vi /etc/sysctl.conf Append a config directive as follows: fs.file-max = 100000 Save and close the file. Users need to log out and log back in again to changes take effect or just type the following command: # sysctl -p Verify your settings with command: # cat /proc/sys/fs/file-max OR # sysctl fs.file-maxUser Level FD LimitsThe above procedure sets system-wide file descriptors (FD) limits. However, you can limit httpd (or any other users) user to specific limits by editing /etc
