Hi, > /etc/security/limits.conf being ignored by pound ? This is not related to pound, but to ubuntu/debian. I've tried that too on my tomcat machines with no effect. I've read a post somewhere (can not find it anymore) that ubuntu/debian does not use limits.conf anymore. Instead have a look on /etc/security/limits.d/ and how to configure that. For me, this is the easy way to go: > adding "ulimit -n 400000" to /etc/init.d/pound" and a restart of pound Kind regards David On 26.02.2013 09:55, Nigel Pallett wrote: > 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. > > On 25/02/13 21:08, Joe Gooch wrote: >> >> And you can tell if it took effect by looking in proc. >> >> >> >> Do a ps awwux |grep pound and find the process id >> >> >> >> Then cat /proc/[process id]/limits >> >> >> >> And verify it took effect. >> >> >> >> Joe >> >> >> >> *From:*Emilio Campos [mailto:[email protected]] >> *Sent:* Monday, February 25, 2013 3:48 PM >> *To:* [email protected] >> *Subject:* Re: [Pound Mailing List] "Too many open files" errors >> running pound 2.5-1.1 on Ubuntu 12.04 >> >> >> >> open a tty console: >> >> ulimit -n 30000 >> >> after in the same console restart pound and try again, the irritating >> message "too many open files" must to disappear. >> >> Regards >> >> Also you can add "ulimit -n 30000" in your init.d script >> >> 2013/2/25 Nigel Pallett <[email protected] >> <mailto:[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. >> >> >> >> On 25/02/13 16:11, Scott McKeown wrote: >> >> Hi Nigel, >> >> OK thats fine. >> >> Do you have 'Alive', 'TimeOut' and 'ConnTo' values set in your >> Global or BackEnd sections? >> 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.
