Ok, I think it is solved. Adding entries in /etc/security/limits.conf and rebooting made no effect, as "cat /proc/[process id]/limits" still showed soft limit 1024 , hard limit 4096 adding "ulimit -n 400000" to /etc/init.d/pound" and a restart of pound did the trick. Thank you to everyone who responded so quickly. The question remains, however, why are changes to /etc/security/limits.conf being ignored by pound ? Regards, Nigel.

Do a ps awwux |grep pound and find the process id Then cat /proc/[process id]/limits And verify it took effect.

Regards Also you can add "ulimit -n 30000" in your init.d script 2013/2/25 Nigel Pallett <[email protected] > Scott, Thank you for the good feedback I have the following settings in the global section: Client 30 Timeout 240 ConnTo 240 Grace 240 Alive 5 Regards, Nigel.

By default the Alive section is 30 seconds and the TimeOut & ConnTo is 15 seconds you may also find that a 'Grace' setting increase may help. Although if you are just terminating an SSL Certificate and then trying to Load Balance over multiple backend servers you may want to have a look at HAProxy and let that do the heavy work instead of Pound. You will also get better debug logging (thats just my opinion though). ~Scott On 25 February 2013 15:48, Nigel Pallett <[email protected] > wrote: Scott, Pound is talking to backend apache webservers (on the 10.10.5.xxx addressess on the logs) configured with the rpaf module to talk back to pound. This has been working successfully for almost two years now. Is it possible that recent changes to the website application being served up by the backends could give rise to these errors ?

However, I could be wrong but a copy of your pound.cfg would help (remove real world IP's etc.) ~Scott On 25 February 2013 14:58, Nigel Pallett <[email protected] > wrote: Hi, I'm running pound 2.5-1.1 on Ubuntu 12.04.2 LTS , and I'm getting lot's of "Too many open files" errors in syslog (See example below) ------------------------------------------------------------------------------------------------------------------------------------------------------ Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3273bc4700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f325330c700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3273bc4700) e503 backend 10.10.5.123:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3270380700) e503 backend 10.10.5.123:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f325b69a700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3271136700) e503 backend 10.10.5.121:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f32712bc700) e503 backend 10.10.5.124:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f32712bc700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3271136700) e503 backend 10.10.5.124:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f325b69a700) e503 backend 10.10.5.124:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f325b69a700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3271136700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f3271136700) e503 backend 10.10.5.124:80 socket create: Too many open files Feb 25 14:53:30 gr-lb01 pound: (7f325b69a700) e503 backend 10.10.5.123:80 socket create: Too many open files Feb 25 14:53:33 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:33 gr-lb01 pound: (7f325a75e700) e503 backend 10.10.5.124:80 socket create: Too many open files Feb 25 14:53:33 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:33 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:33 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:33 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:33 gr-lb01 pound: (7f325a75e700) e503 backend 10.10.5.121:80 socket create: Too many open files Feb 25 14:53:33 gr-lb01 pound: HTTP accept: Too many open files Feb 25 14:53:33 gr-lb01 pound: (7f3272293700) e503 backend 10.10.5.122:80 socket create: Too many open files Feb 25 14:53:33 gr-lb01 pound: (7f3271f46700) e503 backend 10.10.5.124:80 socket create: Too many open files ------------------------------------------------------------------------------------------------------------------------------------------------------ Any Ideas ?
